# Using Skill Seekers with Pinecone
**Last Updated:** February 5, 2026
**Status:** Production Ready
**Difficulty:** Easy ⭐
---
## 🎯 The Problem
Building production-grade vector search applications requires:
- **Scalable Vector Database** - Handle millions of embeddings efficiently
- **Low Latency** - Sub-100ms query response times
- **High Availability** - 99.9% uptime for production apps
- **Easy Integration** - Works with any embedding model
**Example:**
> "When building a customer support bot with RAG, you need to search across 500k+ documentation chunks in <50ms. Managing your own vector database means dealing with scaling, replication, and performance optimization."
---
## ✨ The Solution
Use Skill Seekers to **prepare documentation for Pinecone**:
1. **Generate structured documents** from any source
2. **Create embeddings** with your preferred model (OpenAI, Cohere, etc.)
3. **Upsert to Pinecone** with rich metadata for filtering
4. **Query with context** - Full metadata preserved for filtering and routing
**Result:**
Skill Seekers outputs JSON format ready for Pinecone upsert with all metadata intact.
---
## 🚀 Quick Start (10 Minutes)
### Prerequisites
- Python 3.10+
- Pinecone account (free tier available)
- Embedding model API key (OpenAI or Cohere recommended)
### Installation
```bash
# Install Skill Seekers
pip install skill-seekers
# Install Pinecone client + embeddings
pip install pinecone-client openai
# Or with Cohere embeddings
pip install pinecone-client cohere
```
### Setup Pinecone
```bash
# Get API key from: https://app.pinecone.io/
export PINECONE_API_KEY=your-api-key
# Get OpenAI key for embeddings
export OPENAI_API_KEY=sk-...
```
### Generate Documents
```bash
# Example: React documentation
skill-seekers scrape --config configs/react.json
# Package for Pinecone (uses LangChain format)
skill-seekers package output/react --target langchain
# Output: output/react-langchain.json
```
### Upsert to Pinecone
```python
from pinecone import Pinecone, ServerlessSpec
from openai import OpenAI
import json
# Initialize clients
pc = Pinecone(api_key="your-pinecone-api-key")
openai_client = OpenAI()
# Create index (first time only)
index_name = "react-docs"
if index_name not in pc.list_indexes().names():
pc.create_index(
name=index_name,
dimension=1536, # OpenAI ada-002 dimension
metric="cosine",
spec=ServerlessSpec(cloud="aws", region="us-east-1")
)
# Connect to index
index = pc.Index(index_name)
# Load documents
with open("output/react-langchain.json") as f:
documents = json.load(f)
# Create embeddings and upsert
vectors = []
for i, doc in enumerate(documents):
# Generate embedding
response = openai_client.embeddings.create(
model="text-embedding-ada-002",
input=doc["page_content"]
)
embedding = response.data[0].embedding
# Prepare vector with metadata
vectors.append({
"id": f"doc_{i}",
"values": embedding,
"metadata": {
"text": doc["page_content"][:1000], # Store snippet
"source": doc["metadata"]["source"],
"category": doc["metadata"]["category"],
"file": doc["metadata"]["file"],
"type": doc["metadata"]["type"]
}
})
# Batch upsert every 100 vectors
if len(vectors) >= 100:
index.upsert(vectors=vectors)
vectors = []
print(f"Upserted {i + 1} documents...")
# Upsert remaining
if vectors:
index.upsert(vectors=vectors)
print(f"✅ Upserted {len(documents)} documents to Pinecone")
```
### Query Pinecone
```python
# Query with filters
query = "How do I use hooks in React?"
# Generate query embedding
response = openai_client.embeddings.create(
model="text-embedding-ada-002",
input=query
)
query_embedding = response.data[0].embedding
# Search with metadata filter
results = index.query(
vector=query_embedding,
top_k=3,
include_metadata=True,
filter={"category": {"$eq": "hooks"}} # Filter by category
)
# Display results
for match in results["matches"]:
print(f"Score: {match['score']:.3f}")
print(f"Category: {match['metadata']['category']}")
print(f"Text: {match['metadata']['text'][:200]}...")
print()
```
---
## 📖 Detailed Setup Guide
### Step 1: Create Pinecone Index
```python
from pinecone import Pinecone, ServerlessSpec
pc = Pinecone(api_key="your-api-key")
# Choose dimensions based on your embedding model:
# - OpenAI ada-002: 1536
# - OpenAI text-embedding-3-small: 1536
# - OpenAI text-embedding-3-large: 3072
# - Cohere embed-english-v3.0: 1024
pc.create_index(
name="my-docs",
dimension=1536, # Match your embedding model
metric="cosine",
spec=ServerlessSpec(
cloud="aws",
region="us-east-1" # Choose closest region
)
)
```
**Available regions:**
- AWS: us-east-1, us-west-2, eu-west-1, ap-southeast-1
- GCP: us-central1, europe-west1, asia-southeast1
- Azure: eastus2, westeurope
### Step 2: Generate Skill Seekers Documents
**Option A: Documentation Website**
```bash
skill-seekers scrape --config configs/django.json
skill-seekers package output/django --target langchain
```
**Option B: GitHub Repository**
```bash
skill-seekers github --repo django/django --name django
skill-seekers package output/django --target langchain
```
**Option C: Local Codebase**
```bash
skill-seekers analyze --directory /path/to/repo
skill-seekers package output/codebase --target langchain
```
### Step 3: Create Embeddings Strategy
**Strategy 1: OpenAI (Recommended)**
```python
from openai import OpenAI
client = OpenAI()
def create_embedding(text: str) -> list[float]:
response = client.embeddings.create(
model="text-embedding-ada-002",
input=text
)
return response.data[0].embedding
# Cost: ~$0.0001 per 1K tokens
# Speed: ~1000 docs/minute
# Quality: Excellent for most use cases
```
**Strategy 2: Cohere**
```python
import cohere
co = cohere.Client("your-cohere-api-key")
def create_embedding(text: str) -> list[float]:
response = co.embed(
texts=[text],
model="embed-english-v3.0",
input_type="search_document"
)
return response.embeddings[0]
# Cost: ~$0.0001 per 1K tokens
# Speed: ~1000 docs/minute
# Quality: Excellent, especially for semantic search
```
**Strategy 3: Local Model (SentenceTransformers)**
```python
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
def create_embedding(text: str) -> list[float]:
return model.encode(text).tolist()
# Cost: Free
# Speed: ~500-1000 docs/minute (CPU)
# Quality: Good for smaller datasets
# Note: Dimension is 384 for all-MiniLM-L6-v2
```
### Step 4: Batch Upsert Pattern
```python
import json
from typing import List, Dict
from tqdm import tqdm
def batch_upsert_documents(
index,
documents_path: str,
embedding_func,
batch_size: int = 100
):
"""
Efficiently upsert documents to Pinecone in batches.
Args:
index: Pinecone index object
documents_path: Path to Skill Seekers JSON output
embedding_func: Function to create embeddings
batch_size: Number of documents per batch
"""
# Load documents
with open(documents_path) as f:
documents = json.load(f)
vectors = []
for i, doc in enumerate(tqdm(documents, desc="Upserting")):
# Create embedding
embedding = embedding_func(doc["page_content"])
# Prepare vector
vectors.append({
"id": f"doc_{i}",
"values": embedding,
"metadata": {
"text": doc["page_content"][:1000], # Pinecone limit
"full_text_id": str(i), # Reference to full text
**doc["metadata"] # Preserve all Skill Seekers metadata
}
})
# Batch upsert
if len(vectors) >= batch_size:
index.upsert(vectors=vectors)
vectors = []
# Upsert remaining
if vectors:
index.upsert(vectors=vectors)
print(f"✅ Upserted {len(documents)} documents")
# Verify index stats
stats = index.describe_index_stats()
print(f"Total vectors in index: {stats['total_vector_count']}")
# Usage
batch_upsert_documents(
index=pc.Index("my-docs"),
documents_path="output/react-langchain.json",
embedding_func=create_embedding,
batch_size=100
)
```
### Step 5: Query with Filters
```python
def semantic_search(
index,
query: str,
embedding_func,
top_k: int = 5,
category: str = None,
file: str = None
):
"""
Semantic search with optional metadata filters.
Args:
index: Pinecone index
query: Search query
embedding_func: Embedding function
top_k: Number of results
category: Filter by category
file: Filter by file
"""
# Create query embedding
query_embedding = embedding_func(query)
# Build filter
filter_dict = {}
if category:
filter_dict["category"] = {"$eq": category}
if file:
filter_dict["file"] = {"$eq": file}
# Query
results = index.query(
vector=query_embedding,
top_k=top_k,
include_metadata=True,
filter=filter_dict if filter_dict else None
)
return results["matches"]
# Example queries
results = semantic_search(
index=pc.Index("react-docs"),
query="How do I manage state?",
embedding_func=create_embedding,
category="hooks" # Only search in hooks category
)
for match in results:
print(f"Score: {match['score']:.3f}")
print(f"Category: {match['metadata']['category']}")
print(f"Text: {match['metadata']['text'][:200]}...")
print()
```
---
## 🎨 Advanced Usage
### Hybrid Search (Keyword + Semantic)
```python
# Pinecone sparse-dense hybrid search
from pinecone_text.sparse import BM25Encoder
# Initialize BM25 encoder
bm25 = BM25Encoder()
bm25.fit(documents) # Fit on your corpus
def hybrid_search(query: str, top_k: int = 5):
# Dense embedding
dense_embedding = create_embedding(query)
# Sparse embedding (BM25)
sparse_embedding = bm25.encode_queries(query)
# Hybrid query
results = index.query(
vector=dense_embedding,
sparse_vector=sparse_embedding,
top_k=top_k,
include_metadata=True
)
return results["matches"]
```
### Namespace Management
```python
# Organize documents by namespace
namespaces = {
"stable": documents_v1,
"beta": documents_v2,
"archived": old_documents
}
for ns, docs in namespaces.items():
vectors = prepare_vectors(docs)
index.upsert(vectors=vectors, namespace=ns)
# Query specific namespace
results = index.query(
vector=query_embedding,
top_k=5,
namespace="stable" # Only query stable docs
)
```
### Metadata Filtering Patterns
```python
# Exact match
filter={"category": {"$eq": "api"}}
# Multiple values (OR)
filter={"category": {"$in": ["api", "guides"]}}
# Exclude
filter={"type": {"$ne": "deprecated"}}
# Range (for numeric metadata)
filter={"version": {"$gte": 2.0}}
# Multiple conditions (AND)
filter={
"$and": [
{"category": {"$eq": "api"}},
{"version": {"$gte": 2.0}}
]
}
```
### RAG Pipeline Integration
```python
from openai import OpenAI
openai_client = OpenAI()
def rag_query(question: str, top_k: int = 3):
"""Complete RAG pipeline with Pinecone."""
# 1. Retrieve relevant documents
query_embedding = create_embedding(question)
results = index.query(
vector=query_embedding,
top_k=top_k,
include_metadata=True
)
# 2. Build context from results
context_parts = []
for match in results["matches"]:
context_parts.append(
f"[{match['metadata']['category']}] "
f"{match['metadata']['text']}"
)
context = "\n\n".join(context_parts)
# 3. Generate answer with LLM
response = openai_client.chat.completions.create(
model="gpt-4",
messages=[
{
"role": "system",
"content": "Answer based on the provided context."
},
{
"role": "user",
"content": f"Context:\n{context}\n\nQuestion: {question}"
}
]
)
return {
"answer": response.choices[0].message.content,
"sources": [
{
"category": m["metadata"]["category"],
"file": m["metadata"]["file"],
"score": m["score"]
}
for m in results["matches"]
]
}
# Usage
result = rag_query("How do I create a React component?")
print(f"Answer: {result['answer']}\n")
print("Sources:")
for source in result["sources"]:
print(f" - {source['category']} ({source['file']}) - Score: {source['score']:.3f}")
```

## 💡 Best Practices
### 1. Choose Right Index Configuration
```python
# Serverless (recommended for most cases)
spec=ServerlessSpec(
cloud="aws",
region="us-east-1" # Choose closest to your users
)
# Pod-based (for high throughput, dedicated resources)
spec=PodSpec(
environment="us-east1-gcp",
pod_type="p1.x1", # Small: p1.x1, Medium: p1.x2, Large: p2.x1
pods=1,
replicas=1
)
```
### 2. Optimize Metadata Storage
```python
# Store only essential metadata in Pinecone (max 40KB per vector)
# Keep full text elsewhere (database, object storage)
metadata = {
"text": doc["page_content"][:1000], # Snippet only
"full_text_id": str(i), # Reference to full text
"category": doc["metadata"]["category"],
"source": doc["metadata"]["source"],
# Don't store: full page_content, images, binary data
}
```
### 3. Use Namespaces for Multi-Tenancy
```python
# Per-customer namespaces
namespace = f"customer_{customer_id}"
index.upsert(vectors=vectors, namespace=namespace)
# Query only customer's data
results = index.query(
vector=query_embedding,
namespace=namespace,
top_k=5
)
```
### 4. Monitor Index Performance
```python
# Check index stats
stats = index.describe_index_stats()
print(f"Total vectors: {stats['total_vector_count']}")
print(f"Dimension: {stats['dimension']}")
print(f"Namespaces: {stats.get('namespaces', {})}")
# Monitor query latency
import time
start = time.time()
results = index.query(vector=query_embedding, top_k=5)
latency = time.time() - start
print(f"Query latency: {latency*1000:.2f}ms")
```
### 5. Handle Updates Efficiently
```python
# Update existing vectors (upsert with same ID)
index.upsert(vectors=[{
"id": "doc_123",
"values": new_embedding,
"metadata": updated_metadata
}])
# Delete obsolete vectors
index.delete(ids=["doc_123", "doc_456"])
# Delete by metadata filter
index.delete(filter={"category": {"$eq": "deprecated"}})
```

## 🔥 Real-World Example: Customer Support Bot
```python
import json
from pinecone import Pinecone, ServerlessSpec
from openai import OpenAI
class SupportBotRAG:
def __init__(self, index_name: str):
self.pc = Pinecone()
self.index = self.pc.Index(index_name)
self.openai = OpenAI()
def ingest_docs(self, docs_path: str):
"""Ingest Skill Seekers documentation."""
with open(docs_path) as f:
documents = json.load(f)
vectors = []
for i, doc in enumerate(documents):
# Create embedding
response = self.openai.embeddings.create(
model="text-embedding-ada-002",
input=doc["page_content"]
)
vectors.append({
"id": f"doc_{i}",
"values": response.data[0].embedding,
"metadata": {
"text": doc["page_content"][:1000],
**doc["metadata"]
}
})
if len(vectors) >= 100:
self.index.upsert(vectors=vectors)
vectors = []
if vectors:
self.index.upsert(vectors=vectors)
print(f"✅ Ingested {len(documents)} documents")
def answer_question(self, question: str, category: str = None):
"""Answer customer question with RAG."""
# Create query embedding
response = self.openai.embeddings.create(
model="text-embedding-ada-002",
input=question
)
query_embedding = response.data[0].embedding
# Retrieve relevant docs
filter_dict = {"category": {"$eq": category}} if category else None
results = self.index.query(
vector=query_embedding,
top_k=3,
include_metadata=True,
filter=filter_dict
)
# Build context
context = "\n\n".join([
m["metadata"]["text"] for m in results["matches"]
])
# Generate answer
completion = self.openai.chat.completions.create(
model="gpt-4",
messages=[
{
"role": "system",
"content": "You are a helpful support bot. Answer based on the provided documentation."
},
{
"role": "user",
"content": f"Context:\n{context}\n\nQuestion: {question}"
}
]
)
return {
"answer": completion.choices[0].message.content,
"sources": [
{
"category": m["metadata"]["category"],
"score": m["score"]
}
for m in results["matches"]
]
}
# Usage
bot = SupportBotRAG("support-docs")
bot.ingest_docs("output/product-docs-langchain.json")
result = bot.answer_question("How do I reset my password?", category="authentication")
print(f"Answer: {result['answer']}")
```

## 🐛 Troubleshooting
### Issue: Dimension Mismatch Error
**Problem:** "Dimension mismatch: expected 1536, got 384"
**Solution:** Ensure embedding model dimension matches index
```python
# Check your embedding model dimension
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
print(f"Model dimension: {model.get_sentence_embedding_dimension()}") # 384
# Create index with correct dimension
pc.create_index(name="my-index", dimension=384, ...)
```
### Issue: Rate Limit Errors
**Problem:** "Rate limit exceeded"
**Solution:** Add retry logic and batching
```python
import time
from tenacity import retry, wait_exponential, stop_after_attempt
@retry(wait=wait_exponential(multiplier=1, min=2, max=10), stop=stop_after_attempt(3))
def upsert_with_retry(index, vectors):
return index.upsert(vectors=vectors)
# Use smaller batches
batch_size = 50 # Reduce from 100
```
### Issue: High Query Latency
**Solutions:**
```python
# 1. Reduce top_k
results = index.query(vector=query_embedding, top_k=3) # Instead of 10
# 2. Use metadata filtering to reduce search space
filter={"category": {"$eq": "api"}}
# 3. Use namespaces
namespace="high_priority_docs"
# 4. Consider pod-based index for consistent low latency
spec=PodSpec(environment="us-east1-gcp", pod_type="p1.x2")
```
### Issue: Missing Metadata
**Problem:** Metadata not returned in results
**Solution:** Enable metadata in query
```python
results = index.query(
vector=query_embedding,
top_k=5,
include_metadata=True # CRITICAL
)
```

## 📊 Cost Optimization
### Embedding Costs
| Provider | Model | Cost per 1M tokens | Speed |
|----------|-------|-------------------|-------|
| OpenAI | ada-002 | $0.10 | Fast |
| OpenAI | text-embedding-3-small | $0.02 | Fast |
| OpenAI | text-embedding-3-large | $0.13 | Fast |
| Cohere | embed-english-v3.0 | $0.10 | Fast |
| Local | SentenceTransformers | Free | Medium |
**Recommendation:** OpenAI text-embedding-3-small (best quality/cost ratio)
### Pinecone Costs
**Serverless (pay per use):**
- Storage: $0.01 per GB/month
- Reads: $0.025 per 100k read units
- Writes: $0.50 per 100k write units
**Pod-based (fixed cost):**
- p1.x1: ~$70/month (1GB storage, 100 QPS)
- p1.x2: ~$140/month (2GB storage, 200 QPS)
- p2.x1: ~$280/month (4GB storage, 400 QPS)
**Example costs for 100k documents:**
- Storage: ~250MB = $0.0025/month
- Writes: 100k = $0.50 one-time
- Reads: 100k queries = $0.025/month
