# Knowledge Discovery Text Index and Query

The Knowledge Discovery text index is the main store of text document content.

You can index documents into Knowledge Discovery in two formats:

- Knowledge Discovery IDX format. A Knowledge Discovery-specific plain text format that uses a flat Knowledge Discovery field structure.

- XML format. Standard XML.

You can create documents yourself, or by using Knowledge Discovery ingest and connectors to retrieve and convert files into XML or IDX format.

The Knowledge Discovery text index stores the document concepts (the best terms and phrases), along with fields that contain any additional metadata or enrichment values that you create or configure in your connectors and ingestion workflow.

When you query for documents, Knowledge Discovery finds documents with matching concepts to the query, as well as matching any additional query requirements. It returns a link to the documents that match the query, along with a percentage weight that indicates how relevant the result is to the original query.

Knowledge Discovery returns documents in XML (even if the document was not originally in XML format).

TIP: Knowledge Discovery stores agents, profiles, and categories in a similar way to documents, in the Agentstore component. The query process is similar to that for standard documents.

However, you do not generally need to query Agentstore directly. You send requests for agents and profiles to the Community component, and requests for categories to the Category component. These components then query the Agentstore component for you and return the relevant results.
