The program incorrectly detects films if the title consists of both Russian and English titles. For example:
Шерлок Холмс.Sherlock.Holmes.2009.1080p.mkv
Солдат Soldier 1998.BDRip.720p.mkv
The program either does not find the film at all or finds it wrong. For example, for such a movie
Шерлок Холмс.Sherlock.Holmes.2009.1080p.mkv
she indicated this one: Snatch (Snatch (2000) - IMDb )
how can i fix this? don’t want to rename all files. 
You’re going to have to change the file name in one way or another. Either you can add the year after the Russian title but before the English title like
“Шерлок Холмс.2009.Sherlock.Holmes.2009.1080p.mkv” This may work but the one sure fix is to stick with one language in the file names. Infuse looks for a title then year for movies and when you double the title before the year Infuse is searching for a match that also has the title doubled which it won’t find.
Sorry but renaming is going to be needed one way or the other.
