A file uploaded but cannot be retrieved: how do you check parsing, indexing and querying?

Locate the uploaded record with a stable document identifier

This applies when a file is marked received but knowledge-base answers report no information. Select a small non-sensitive file with a distinctive test sentence and record the intended knowledge base and index. Upload, parsing completion and searchable indexing may be separate states; an upload-success screenshot does not verify the entire pipeline.

Inspect parsed output and index fields in order

Check whether parsing produced body text or left a scanned file empty. Query the index directly by document ID and inspect chunk fields, vector dimensions and mappings. Finally diagnose business filters within the authorized scope, checking whether date or department conditions exclude the document. Do not remove user access restrictions to obtain extra material.

Start with direct queries to isolate the failing stage

Fix extraction or OCR when parsing is empty; fix mappings and reprocess in a test index when fields are missing. If direct lookup works but semantic querying fails, check the query embedding model and dimensions and compare keyword retrieval. Change one stage at a time and preserve task status and output, so conclusions reflect the data pipeline rather than an incidental hit after another upload.

Test both original wording and natural paraphrases

First ask an explicit question containing the test sentence and confirm chunk retrieval, then use a natural paraphrase to find the same evidence. The answer must match the source with an accessible citation. Also ask about information absent from the file, checking that healthy indexing does not lead to unconditional answers. Increased upload counts are not completion evidence.

This article uploaded no private files or rebuilt any production index; the method can be exercised with isolated samples. Processing delays and error states vary by service, so use actual task records. If parsed output or index inspection is unavailable, ask the maintainer to investigate. An empty answer alone cannot identify the failing stage.
