Yes, as it ignores case and assumes you've just given it words (don't you 
have to have "and" in upper case, though? You said you had FLAG_BOOLEAN, not 
FLAG_BOOLEAN_ANY_CASE).

Just don't tell them about it? :) Have something stupid, e.g.:

     add_prefix("wangleflooble", "XZ")

and then convert "IIS and sharp" into "wangleflooble:IIS and sharp" before 
feeding to QueryParser.
