Thanks. Yes, I mean multi valued fileds, but I am still confused how to use it.
BTW, I also found another class MultiFieldQueryParser. If I don't use multi valued fields, it seems I can use this class to compose a query over multiple fields. But is there difference of the result returned with these two methods? Or the performance difference? cheers, W.
