Clozemaster has a really nice feature that lets you select the words of a sentence and find the corresponding sentence on Tatoeba. However, wth this sentence:
Молодёжь знает правила, а старики - исключения.
the search didn’t work unless I stripped out the dash (a simple hyphen) from the search field once I landed on Tatoeba. The problem is that several punctuation marks have meanings in Manticore, the search engine used by Tatoeba. A hyphen is one of them: it indicates that sentences containing the following word should not be matched.
Since Clozemasters (or whatever you want to call people who hang out at Clozemaster) will probably never want to use these special marks when they’re searching Tatoeba for a sentence they’ve just selected, would it make sense to strip out all punctuation before a search?
