How does semantic search work?
Semantic search relies on document indexing, chunking, vectorization, a retrieval engine, and an answer that points back to the right sources instead of merely generating free text.
Compatible documents
The engine can process PDFs, DOCX, HTML pages, knowledge bases, tickets, internal notes, FAQ, structured exports, or versioned business documents.
Knowledge updates
The real issue is not the initial indexing, but the ability to reindex cleanly when a version changes, when a source disappears, or when a new base becomes a priority.
Security
Security depends on source permissions, result filtering, logging of sensitive queries, and control over engine and embedding hosting.
