You are developing a document management system with extensive text-based content. How would you implement indexing and full-text search to ensure efficient and relevant retrieval of documents based on user queries?

To efficiently retrieve documents in a text-based document management system, you should use Inverted Indexes for keywords and implement a Full-Text Search Engine. This approach allows users to search for documents based on their content efficiently. Creating a single index for all document metadata may not provide efficient text-based retrieval. Simple SQL queries may not handle complex text searches effectively. Disabling indexing entirely would severely impact search performance.
