1) Choose a file, preferably with a simple but rare title: https://commons.wikimedia.org/wiki/Special:Random/File
2) Enter it in the search bar and choose the "search" (not "go") option, or equivalent, e.g. https://www.mediawiki.org/w/index.php?title=Special%3ASearch&search=File%3ASom+tam+pu.jpg&fulltext=Search&srbackend=CirrusSearch
2-bis) A) Visit the multimedia search tab: <https://www.mediawiki.org/w/index.php?title=Special:Search&search=&fulltext=Search&profile=images&redirs=1>
B) Search the full filename (without File: prefix), optionally quoted, and try a few times till you get what you should...
I) Actual result: « There were no results matching the query. There is a page named "File:Som tam pu.jpg" on this wiki.»
II) Expected result: the file is among search results (together with other matching filenames if you've not used the quotes). <https://www.mediawiki.org/w/index.php?title=Special%3ASearch&search=File%3ASom+tam+pu.jpg&fulltext=Search>
II-bis) Same but at https://www.mediawiki.org/w/index.php?title=Special%3ASearch&profile=images&search=Som+tam+pu.jpg&fulltext=Search
