Functionality

This module is designed to answer a user query based on documents ingested into the knowledge center. The module will first create a search string from the user question, embed it, and then perform a semantic search or a full text search in the VectorDB or the PostgreSQL DB. Finally, the module generates an answer for the user input based on retrieved internal knowledge, either referencing this knowledge with appropriate documents or stating that no information was found in the internal system.

Input

A user question related to information within the document database.

Example input:

"What is the guideline saying about travels to Europe?"

Output

An answer based on internal knowledge, either referencing the appropriate documents or stating that no information was found in the internal system.
