Hello Chris, Thanks a lot for the helping hand.
I plugged in MaxDisjunctQuery and it is working so far, but I need to check accuracy of it. Next problem I met is highlighter, which must be adopted to understand MaxDisjunctQuery(because now it stops to highlight anything due to unknown new Query type), but this is yet another story :).
