Does not find all subtitles

[gattilorenz]

When using drag-n-drop to find subtitles, sometimes there are no results:

I'm assuming that Caption is using the hash of the video to find them, in this case. However, if I do type the name of the file, I can get the results I was looking for, between less relevant stuff:

So I guess in the first case it would be useful to either directly search for filename (removing the extension, of course, but in general replacing dashes or dots with spaces could help I guess), or at least show somewhere a prompt/hint for the user that once clicked does that.
