Weaviate Integration with Skill Seekers

Status: ✅ Production Ready Difficulty: Intermediate Last Updated: February 7, 2026

❌ The Problem

Building RAG applications with Weaviate involves several challenges:

1. Manual Data Schema Design - Need to define GraphQL schemas and object properties manually for each documentation project
2. Complex Hybrid Search - Setting up both BM25 keyword search and vector search requires understanding Weaviate's query language
3. Multi-Tenancy Configuration - Properly isolating different documentation sets requires tenant management

Example Pain Point:

# Manual schema creation for each framework
client.schema.create_class({
    "class": "ReactDocs",
    "properties": [
        {"name": "content", "dataType": ["text"]},
        {"name": "category", "dataType": ["string"]},
        {"name": "source", "dataType": ["string"]},
        # ... 10+ more properties
    ],
    "vectorizer": "text2vec-openai",
    "moduleConfig": {
        "text2vec-openai": {"model": "ada-002"}
    }
})

✅ The Solution

Skill Seekers automates Weaviate integration with structured, production-ready data:

Benefits:

• ✅ Auto-formatted objects with all metadata properties
• ✅ Consistent schema across all frameworks
• ✅ Compatible with hybrid search (BM25 + vector)
• ✅ Works with Weaviate Cloud Services (WCS) and self-hosted
• ✅ Supports multi-tenancy for documentation isolation

Result: 10-minute setup, production-ready vector search with enterprise features.

⚡ Quick Start (5 Minutes)

Prerequisites

# Install Weaviate Python client
pip install weaviate-client>=3.25.0

# Or with Skill Seekers
pip install skill-seekers[all-llms]

What you need:

• Weaviate instance (WCS or self-hosted)
• Weaviate API key (if using WCS)
• OpenAI API key (for embeddings)

Generate Weaviate-Ready Documents

# Step 1: Scrape documentation
skill-seekers scrape --config configs/react.json

# Step 2: Package for Weaviate (creates LangChain format)
skill-seekers package output/react --target langchain

# Output: output/react-langchain.json (Weaviate-compatible)

Upload to Weaviate

import weaviate
import json

# Connect to Weaviate
client = weaviate.Client(
    url="https://your-instance.weaviate.network",
    auth_client_secret=weaviate.AuthApiKey(api_key="your-api-key"),
    additional_headers={
        "X-OpenAI-Api-Key": "your-openai-key"
    }
)

# Create schema (first time only)
client.schema.create_class({
    "class": "Documentation",
    "vectorizer": "text2vec-openai",
    "moduleConfig": {
        "text2vec-openai": {"model": "ada-002"}
    }
})

# Load documents
with open("output/react-langchain.json") as f:
    documents = json.load(f)

# Batch upload
with client.batch as batch:
    for i, doc in enumerate(documents):
        properties = {
            "content": doc["page_content"],
            "source": doc["metadata"]["source"],
            "category": doc["metadata"]["category"],
            "file": doc["metadata"]["file"],
            "type": doc["metadata"]["type"]
        }
        batch.add_data_object(properties, "Documentation")

        if (i + 1) % 100 == 0:
            print(f"Uploaded {i + 1} documents...")

print(f"✅ Uploaded {len(documents)} documents to Weaviate")

Query with Hybrid Search

# Hybrid search: BM25 + vector similarity
result = client.query.get("Documentation", ["content", "category"]) \
    .with_hybrid(
        query="How do I use React hooks?",
        alpha=0.75  # 0=BM25 only, 1=vector only, 0.5=balanced
    ) \
    .with_limit(3) \
    .do()

for item in result["data"]["Get"]["Documentation"]:
    print(f"Category: {item['category']}")
    print(f"Content: {item['content'][:200]}...")
    print()

Step 3: Create Weaviate Schema

import weaviate

client = weaviate.Client(
    url="https://your-instance.weaviate.network",
    auth_client_secret=weaviate.AuthApiKey(api_key="your-api-key"),
    additional_headers={
        "X-OpenAI-Api-Key": "your-openai-key"
    }
)

# Define schema with all Skill Seekers metadata
schema = {
    "class": "Documentation",
    "description": "Framework documentation from Skill Seekers",
    "vectorizer": "text2vec-openai",
    "moduleConfig": {
        "text2vec-openai": {
            "model": "ada-002",
            "vectorizeClassName": False
        }
    },
    "properties": [
        {
            "name": "content",
            "dataType": ["text"],
            "description": "Documentation content",
            "moduleConfig": {
                "text2vec-openai": {"skip": False}
            }
        },
        {
            "name": "source",
            "dataType": ["string"],
            "description": "Framework name"
        },
        {
            "name": "category",
            "dataType": ["string"],
            "description": "Documentation category"
        },
        {
            "name": "file",
            "dataType": ["string"],
            "description": "Source file"
        },
        {
            "name": "type",
            "dataType": ["string"],
            "description": "Document type"
        },
        {
            "name": "url",
            "dataType": ["string"],
            "description": "Original URL"
        }
    ]
}

# Create class (idempotent)
try:
    client.schema.create_class(schema)
    print("✅ Schema created")
except Exception as e:
    print(f"Schema already exists or error: {e}")

Step 4: Batch Upload Documents

import json
from weaviate.util import generate_uuid5

# Load documents
with open("output/django-langchain.json") as f:
    documents = json.load(f)

# Configure batch
client.batch.configure(
    batch_size=100,
    dynamic=True,
    timeout_retries=3,
)

# Upload with batch
with client.batch as batch:
    for i, doc in enumerate(documents):
        properties = {
            "content": doc["page_content"],
            "source": doc["metadata"]["source"],
            "category": doc["metadata"]["category"],
            "file": doc["metadata"]["file"],
            "type": doc["metadata"]["type"],
            "url": doc["metadata"].get("url", "")
        }

        # Generate deterministic UUID
        uuid = generate_uuid5(properties["content"])

        batch.add_data_object(
            data_object=properties,
            class_name="Documentation",
            uuid=uuid
        )

        if (i + 1) % 100 == 0:
            print(f"Uploaded {i + 1}/{len(documents)} documents...")

print(f"✅ Uploaded {len(documents)} documents to Weaviate")

# Verify upload
result = client.query.aggregate("Documentation").with_meta_count().do()
count = result["data"]["Aggregate"]["Documentation"][0]["meta"]["count"]
print(f"Total documents in Weaviate: {count}")

Step 5: Query with Filters

# Hybrid search with category filter
result = client.query.get("Documentation", ["content", "category", "source"]) \
    .with_hybrid(
        query="How do I create a Django model?",
        alpha=0.75
    ) \
    .with_where({
        "path": ["category"],
        "operator": "Equal",
        "valueString": "models"
    }) \
    .with_limit(5) \
    .do()

for item in result["data"]["Get"]["Documentation"]:
    print(f"Source: {item['source']}")
    print(f"Category: {item['category']}")
    print(f"Content: {item['content'][:200]}...")
    print()

🚀 Advanced Usage

1. Multi-Tenancy for Framework Isolation

# Enable multi-tenancy on schema
client.schema.update_config("Documentation", {
    "multiTenancyConfig": {"enabled": True}
})

# Add tenants
client.schema.add_class_tenants(
    class_name="Documentation",
    tenants=[
        {"name": "react"},
        {"name": "django"},
        {"name": "fastapi"}
    ]
)

# Upload to specific tenant
with client.batch as batch:
    batch.add_data_object(
        data_object={"content": "...", "category": "hooks"},
        class_name="Documentation",
        tenant="react"
    )

# Query specific tenant
result = client.query.get("Documentation", ["content"]) \
    .with_tenant("react") \
    .with_hybrid(query="React hooks") \
    .do()

2. Named Vectors for Multiple Embeddings

# Schema with multiple vector spaces
schema = {
    "class": "Documentation",
    "vectorizer": "text2vec-openai",
    "vectorConfig": {
        "content": {
            "vectorizer": {
                "text2vec-openai": {"model": "ada-002"}
            }
        },
        "title": {
            "vectorizer": {
                "text2vec-openai": {"model": "ada-002"}
            }
        }
    },
    "properties": [
        {"name": "content", "dataType": ["text"]},
        {"name": "title", "dataType": ["string"]}
    ]
}

# Query specific vector
result = client.query.get("Documentation", ["content", "title"]) \
    .with_near_text({"concepts": ["authentication"]}, target_vector="content") \
    .do()

3. Generative Search (RAG in Weaviate)

# Answer questions using Weaviate's generative module
result = client.query.get("Documentation", ["content", "category"]) \
    .with_hybrid(query="How do I use Django middleware?") \
    .with_generate(
        single_prompt="Explain this concept: {content}",
        grouped_task="Summarize Django middleware based on these docs"
    ) \
    .with_limit(3) \
    .do()

# Access generated answer
answer = result["data"]["Get"]["Documentation"][0]["_additional"]["generate"]["singleResult"]
print(f"Generated Answer: {answer}")

4. GraphQL Cross-References

# Create relationships between documentation
schema = {
    "class": "Documentation",
    "properties": [
        {"name": "content", "dataType": ["text"]},
        {"name": "relatedTo", "dataType": ["Documentation"]}  # Cross-reference
    ]
}

# Link related docs
client.data_object.reference.add(
    from_class_name="Documentation",
    from_uuid=doc1_uuid,
    from_property_name="relatedTo",
    to_class_name="Documentation",
    to_uuid=doc2_uuid
)

# Query with references
result = client.query.get("Documentation", ["content", "relatedTo {... on Documentation {content}}"]) \
    .with_hybrid(query="React hooks") \
    .do()

5. Backup and Restore

# Backup all data
backup_name = "docs-backup-2026-02-07"
result = client.backup.create(
    backup_id=backup_name,
    backend="filesystem",
    include_classes=["Documentation"]
)

# Wait for completion
status = client.backup.get_create_status(backup_id=backup_name, backend="filesystem")
print(f"Backup status: {status['status']}")

# Restore from backup
result = client.backup.restore(
    backup_id=backup_name,
    backend="filesystem",
    include_classes=["Documentation"]
)

📋 Best Practices

1. Choose the Right Alpha Value

# Alpha controls BM25 vs vector balance
# 0.0 = Pure BM25 (keyword matching)
# 1.0 = Pure vector (semantic search)
# 0.75 = Recommended (75% semantic, 25% keyword)

# For exact terms (API names, functions)
result = client.query.get(...).with_hybrid(query="useState", alpha=0.3).do()

# For conceptual queries
result = client.query.get(...).with_hybrid(query="state management", alpha=0.9).do()

# Balanced (recommended default)
result = client.query.get(...).with_hybrid(query="React hooks", alpha=0.75).do()

2. Use Tenant Isolation for Multi-Framework

# Separate tenants prevent cross-contamination
tenants = ["react", "vue", "angular", "svelte"]

for tenant in tenants:
    client.schema.add_class_tenants("Documentation", [{"name": tenant}])

# Query only React docs
result = client.query.get("Documentation", ["content"]) \
    .with_tenant("react") \
    .with_hybrid(query="components") \
    .do()

3. Monitor Performance

# Check cluster health
health = client.cluster.get_nodes_status()
print(f"Nodes: {len(health)}")
for node in health:
    print(f"  {node['name']}: {node['status']}")

# Monitor query performance
import time
start = time.time()
result = client.query.get("Documentation", ["content"]).with_limit(10).do()
latency = time.time() - start
print(f"Query latency: {latency*1000:.2f}ms")

# Check object count
stats = client.query.aggregate("Documentation").with_meta_count().do()
count = stats["data"]["Aggregate"]["Documentation"][0]["meta"]["count"]
print(f"Total objects: {count}")

4. Handle Updates Efficiently

from weaviate.util import generate_uuid5

# Update existing object (idempotent UUID)
uuid = generate_uuid5("unique-content-identifier")
client.data_object.replace(
    data_object={"content": "updated content", ...},
    class_name="Documentation",
    uuid=uuid
)

# Delete obsolete objects
client.data_object.delete(uuid=uuid, class_name="Documentation")

# Delete by filter
client.batch.delete_objects(
    class_name="Documentation",
    where={
        "path": ["category"],
        "operator": "Equal",
        "valueString": "deprecated"
    }
)

5. Use Async for Large Uploads

import asyncio
from weaviate import Client

async def upload_batch(client, documents, start_idx, batch_size):
    """Upload documents asynchronously."""
    with client.batch as batch:
        for i in range(start_idx, min(start_idx + batch_size, len(documents))):
            doc = documents[i]
            properties = {
                "content": doc["page_content"],
                **doc["metadata"]
            }
            batch.add_data_object(properties, "Documentation")

async def upload_all(documents, batch_size=100):
    client = Client(url="...", auth_client_secret=...)

    tasks = []
    for i in range(0, len(documents), batch_size):
        tasks.append(upload_batch(client, documents, i, batch_size))

    await asyncio.gather(*tasks)
    print(f"✅ Uploaded {len(documents)} documents")

# Usage
asyncio.run(upload_all(documents))

🐛 Troubleshooting

Issue: Connection Failed

Problem: "Could not connect to Weaviate at http://localhost:8080"

Solutions:

1. Check Weaviate is running:

docker ps | grep weaviate
curl http://localhost:8080/v1/meta

2. Verify URL format:

# Local: no https
client = weaviate.Client("http://localhost:8080")

# WCS: use https
client = weaviate.Client("https://your-cluster.weaviate.network")

3. Check authentication:

# WCS requires API key
client = weaviate.Client(
    url="https://your-cluster.weaviate.network",
    auth_client_secret=weaviate.AuthApiKey(api_key="your-key")
)

Issue: Schema Already Exists

Problem: "Class 'Documentation' already exists"

Solutions:

1. Delete and recreate:

client.schema.delete_class("Documentation")
client.schema.create_class(schema)

2. Update existing schema:

client.schema.add_class_properties("Documentation", new_properties)

3. Check existing schema:

existing = client.schema.get("Documentation")
print(json.dumps(existing, indent=2))

Issue: Embedding API Key Not Set

Problem: "Vectorizer requires X-OpenAI-Api-Key header"

Solution:

client = weaviate.Client(
    url="https://your-cluster.weaviate.network",
    additional_headers={
        "X-OpenAI-Api-Key": "sk-..."  # OpenAI key
        # or "X-Cohere-Api-Key": "..."
        # or "X-HuggingFace-Api-Key": "..."
    }
)

Issue: Slow Batch Upload

Problem: Uploading 10,000 docs takes >10 minutes

Solutions:

1. Enable dynamic batching:

client.batch.configure(
    batch_size=100,
    dynamic=True,  # Auto-adjust batch size
    timeout_retries=3
)

2. Use parallel batches:

from concurrent.futures import ThreadPoolExecutor

def upload_chunk(docs_chunk):
    with client.batch as batch:
        for doc in docs_chunk:
            batch.add_data_object(doc, "Documentation")

with ThreadPoolExecutor(max_workers=4) as executor:
    chunk_size = len(documents) // 4
    chunks = [documents[i:i+chunk_size] for i in range(0, len(documents), chunk_size)]
    executor.map(upload_chunk, chunks)

Issue: Hybrid Search Not Working

Problem: "with_hybrid() returns no results"

Solutions:

1. Check vectorizer is enabled:

schema = client.schema.get("Documentation")
print(schema["vectorizer"])  # Should be "text2vec-openai" or similar

2. Try pure vector search:

# Test vector search works
result = client.query.get("Documentation", ["content"]) \
    .with_near_text({"concepts": ["test query"]}) \
    .do()

3. Verify BM25 index:

# BM25 requires inverted index
schema["invertedIndexConfig"] = {"bm25": {"enabled": True}}
client.schema.update_config("Documentation", schema)

Issue: Tenant Not Found

Problem: "Tenant 'react' does not exist"

Solutions:

1. List existing tenants:

tenants = client.schema.get_class_tenants("Documentation")
print([t["name"] for t in tenants])

2. Add missing tenant:

client.schema.add_class_tenants("Documentation", [{"name": "react"}])

3. Check multi-tenancy is enabled:

schema = client.schema.get("Documentation")
print(schema.get("multiTenancyConfig", {}).get("enabled"))  # Should be True

📊 Before vs. After

🎯 Next Steps

Enhance Your Weaviate Integration

1. Add Generative Search:

   # Enable qna-openai module in Weaviate
   # Then use with_generate() for RAG
   

2. Implement Semantic Chunking:

   skill-seekers scrape --config configs/fastapi.json --chunk-for-rag --chunk-size 512
   

3. Set Up Multi-Tenancy:

   • Create tenant per framework
   • Query with .with_tenant("framework-name")
   • Isolate different documentation sets

4. Monitor Performance:

   • Track query latency
   • Monitor object count
   • Check cluster health
