Quick Overview

Knowledge bases let your agents access information from multiple sources like files, websites, and cloud storage. When your agent needs information, it searches through all your content using both semantic understanding and keyword matching to find relevant answers. This is perfect for customer support bots that need to reference documentation, or any workflow where your agent needs to pull information from a large collection of content.
For small datasets (single Google Doc or Sheet), use direct actions like Get Document or Get Spreadsheet for better performance.

How Search Works

Matches meaning rather than exact words. Understands context and finds related concepts.
  • Query: “dark colored jeans”
  • Finds: “black and navy denim pants”
Matches exact words in your query. Useful for precise matching of specific terms.
  • Query: “invoice #12345”
  • Finds: Exact invoice number

Query Field

Instructions for what to search in the knowledge base. Mode options:
  • Auto — Your agent determines the optimal query
  • Prompt AI - Custom search instructions
  • Set Manually - Use exact search query (no AI)
Example: Search for the answer to the user's question in the email

Max Results

Number of results returned per query.
  • Default: 4 results
  • Maximum: 10 results
  • Increase for frequently mentioned topics

Search Fuzziness

Balance between semantic and keyword search (0-100 scale).
  • 0 - Pure keyword matching
  • 100 - Pure semantic search (default)
  • Lower values emphasize exact matches
Keep fuzziness at 100 to avoid the 1,500 file limit. Lower values restrict search to first 1,500 files only.

Managing Your Knowledge Base

Your knowledge base stays current through automatic and manual updates:
  • Automatic updates: Content refreshes every 24 hours automatically
  • Manual updates: For immediate updates, use Resync Knowledge Base actions to update the entire knowledge base or specific entries when needed

Best Practices

  • Organize content - Group similar information and remove duplicates
  • Test queries - Try different searches and adjust fuzziness for accuracy
  • Update regularly - Keep content current with manual resyncs when needed
  • Start simple - Begin with fewer sources and expand as needed

Common Use Cases

Troubleshooting

Pro users have 20M character limit. Monitor usage to avoid hitting storage limits.
