I'm attempting to create a profanity filter. I thought to use a QueryFilter created with a Query of (-$#!+ AND [EMAIL PROTECTED] AND etc). The problem I have run into is that, as a pure negative query is not supported (a query for (-term) DOES NOT return the inverse of a query for (term)), I believe the bit set returned by a purely negative QueryFilter is empty, so no matter how many results returned by the initial query, the result after filtering is always zero documents.
I was wondering if anyone had suggestions as to how else to do this. I've considered simply amending the query string submitted by the user to include a pre-generated String that would exclude the query terms, but I consider this a non-elegant solution. I had also thought about creating a new sub-class of QueryFilter, NegativeQueryFilter. Basically, it would works just like a QueryFilter, taking a positive query (so, I would pass it an OR'ed list of profane words), then the resulting bits are simply flipped. I think this would work, unless I'm missing something. I'm going to experiment with it, I'd appreciate anyone's thoughts on this.
