Yeah, since I will need to toggle selectively, it may not work. Also as for writing customized query subclasses, only way I can think of is to create several queries with all possible upper/lower case combinations of the main query, which may really degrade the performance. Creating two different indexes means more overhead for maintaining the index with new docs coming in. Creating two separate fields sounds to be the better option.
