Difficulty creating proper RavenDB query -

i trying implement logic below in ravendb query, receive

system.notsupportedexception: not understand expression

related scores.any expression. understand why is, i'm having hard time coming working option.

public iravenqueryable<person> apply(iravenqueryable<person> query) {     var scores = new list<string>();     if (_a) scores.add("a");     if (_b) scores.add("b");     if (_c) scores.add("c");     if (_u)     {         scores.add("");         scores.add(" ");         scores.add("\t");         scores.add(null);     }      return p in query            scores.any(score => score == p.score)            select p; } 

the trick ravendb linq provider isn't operating on list scores.any() makes 0 sense -- compiles can see dies @ runtime.

the trick reverse field bit , ask if p.score in array of scores if recall correctly.
