# reindexKnowledgeSource

> Trigger an immediate re-index of a knowledge source. Use this when the source content has changed
and you do not want to wait for the automatic weekly re-index. The knowledge source status is reset
to pending and indexing is queued asynchronously. Requires Plain AI to be enabled on the workspace.
