Indexing is stuck or failed

1. Refresh the document list to obtain the latest returned status.
2. Distinguish RUNNING, CANCELLING, and FAIL; elapsed time alone does not redefine the state.
3. If the status is FAIL, open any returned error and use the available retry or reprocessing action.
4. If you changed chunking, allow reprocessing to finish before testing retrieval.
5. Do not delete and re-add the original Document Library file unless you have confirmed that replacement is necessary.

During rechunking, prior manual chunk edits can be overwritten and the document can be temporarily unavailable to retrieval. There is no documented universal resume action for every state.
