Summary

This PR improves the Weaviate knowledge guide by adding:

  • A dedicated "Required Environment Variables" section
  • A troubleshooting section for common setup and usage issues
  • Guidance for authentication problems
  • Guidance for empty search results
  • Guidance for OpenAI integration issues
  • Guidance for retrieval performance troubleshooting

Why

The guide already provides connection, search, RAG, schema, and best-practice documentation. These additions make onboarding easier for new users and help reduce common setup and debugging issues.

Changes

  • Added environment variable reference table
  • Added troubleshooting documentation
  • Kept changes documentation-only and self-contained

Summary by CodeRabbit

  • Documentation
    • Updated README with a required environment variables section for easier setup configuration.
    • Added comprehensive troubleshooting section covering common issues including authentication, search results, integration problems, and performance optimization.

Use "factory farm" instead of "factory farming" for precision.

When referring to investigation techniques, "factory farm investigation techniques" more precisely describes investigating the facilities rather than the abstract practice. As per coding guidelines, prefer 'factory farm' terminology for clarity.

Rephrase to avoid repetitive sentence structure.

Three consecutive sentences begin with "Verify that", which degrades readability. Consider varying the structure. As per static analysis.
