mSearch2 extra / phpMorphy - Any feedback ?

I'm searching for feedback about mSearch2 extra, especially in comparison with advSearch or solution based on getResources and pdoResources.

According information provided on Modstore.pro msearch2 use Morphological search with morphological analyzer library :

http://phpmorphy.sourceforge.net/dokuwiki (Russian)
https://sourceforge.net/projects/phpmorphy/
https://books.google.fr/books?id=plU0DwAAQBAJ&pg=PA684&dq=phpMorphy&hl=fr&sa=X&ved=0ahUKEwiV19-DstjaAhXG7BQKHRyaCfIQ6AEIJzAA#v=onepage&q=phpMorphy&f=false

I am very curious about how phpMorphy works.

The library supports currently Russian, English and German languages. Then what will happen if a non-supported language is used with mSearch2 -- French for example ?
