If HoudahSpot fails to find a file that you know exists on your Mac, the cause is almost always a problem with the Spotlight index. Because HoudahSpot relies on Spotlight, missing or corrupted index entries can cause files to disappear from results.
This guide covers the causes and fixes that are specific to HoudahSpot. For general Spotlight indexing problems – the kind that affect Finder, Spotlight, and every app that relies on the system index – see our companion guide: Why Spotlight on macOS Can’t Find Files.
Why files sometimes disappear from results

- With a corrupted index, the file may vanish without reappearing. This requires an index rebuild. Refer to the linked guide above for full rebuild instructions.
