It seems to me that the search index for MediaSearch on commons is not updated when a file is replaced.
**Steps to reproduce**
1. Upload an image with a resolution of [[ https://commons.wikimedia.org/wiki/File:ZOB_Hannover,_VW_Tower,_Lister_Dreieck.jpg | for example 2,048 × 1,536 Pixels ]]
2. Search in MediaSearch with a CirrusSearch query that finds you image by filesize, for example [[ https://commons.wikimedia.org/wiki/Special:MediaSearch?type=image&q=user%3ADiscostu+filew%3A%3C2049+fileh%3A%3C2049&sort=recency | user:Discostu filew:<2049 fileh:<2049 ]]
3. Overwrite your image with a larger file, for example 3,648 × 2,736 pixels
4. Repeat the same search with MediaSearch
**Expected results**
The image is not among the search results anymore
**Actual results**
The image is still among the search results, even 12 hours after the re-upload
