Still being in a free trial month, I'm not complaining, but thought I should bring these to someone's attention... In the matter of a few minutes of "playing with" Concordance I notices a few mistakes/bugs.
Firstly, it's recognizing a transliterated Hebrew word as being French!

Secondly, it's not accurately combining all word forms.

If there's a better place to report these inconsistencies I'd be happy to know.
I'm very excited about the potential of this tool!
