What variety of Berber does Tatoeba's "Berber" refer to?

Some languages have only one active contributor. If I ever decided to stop visiting this website, then I would have no one hand my sentences over to, because I'm the only active Lithuanian speaker. In which case, I would probably just disown my sentences.

Mnie tez zawsze mowi "Wtyczka QuickTime ulegla awarii". To musi byc cos zwionzane z QuickTime a nie z Tatoeba...

Yeah, I also found this website while looking for Finnish example sentences, and it has been a great help!

Is there any way to look for exactly the word you need? By which I mean, when I look for sentences with "jossa" I find plenty of sentences with "jos" too, and then need to scroll though the hundred example sentences I got, most of which feature "jos", to fish out the sentences with "jossa".

In this case, it's not too catastrophic, but sometimes I search for a word and get over a thousand of example sentences, and most of those sentences do not feature the *exact* word I need.

So is there a way to search for example sentences that only feature exactly the word I need?
