Soulseek don't search for every entry of my wish list

Hello,

I see in the diagnostic that Slsk don't search for all the things I wrote in my wishlist.
It's like he don't research for the same entry. No special character etc...

One example :
Armando power bass

I tried several things but nothing works (Delete, wrote again, case etc...). I had perhaps 30 or 40 entry.
The only solution was to delete all my wish list and just let one or two things.

Like that slsk search for everything.

Is it normal ? Is there a limitation in the wish list ?
