Hi, Don't worry! there always are ways! Is prefix query is what you are trying to run? They would run but would be highly unoptimized as lucene stores terms in a lexically sorted manner in its index. <term>* like query terms are allowed by the parser/searcher though. Possible solution for this would be: Index flipped terms (using an appropriate analyzer) i.e. cat is also indexed as tac. You may then query on ta* instead of at*. Does that solve your issues/concern?
