QdrantService class

The QdrantService class is defined within backend/app/services/qdrant_service.py. QuestionRouter depends on QdrantService but changed its initialization to lazy loading to prevent startup delays. QuestionRouter uses QdrantService for semantic search and retrieving relevant document chunks when processing textual or hybrid queries. QdrantService calls Ollama embedding API to transform texts into vector embeddings used for semantic search. QdrantService connects to and manages a Qdrant vector database instance hosted at 176.9.90.154 for semantic search.

QdrantService connects to and manages a Qdrant vector database instance hosted at 176.9.90.154 for semantic search. TableIndexService uses QdrantService to build semantic search indices for database tables. QuestionRouter now initializes QdrantService lazily instead of at startup to avoid delays during startup and allow immediate request handling without waiting for Qdrant health status. The search method is part of the Qdrant Service.
