One of my biggest problem was the unability of lucene to search with wildcard. Also I have develop my own MultiTermQueries. Now there's a standard class for this, but you'll allways become an exception if your search is to generic, 'a*' for exemple. I can't solve this problem, but I making it acceptable with the follwing allgorithm: - getting all possible terms. - sort them (actualy with the length difference beetween search term (if you search 'TooMany*' then 'TooManyDog' has a better range than 'TooManyClauses')). - get the allowed (I want my BooleanQuery not to overwrite 100 terms for example). - search this. for this Query I can call call: .getWarnnigs() give me a string with a description of the limitation ("Have found 265654 terms for you search please be more precise.") .getTermsList() the list of all searched terms (usefull too for the user). So I can allways have a result. Mostly, with the sorting I am getting the searched term (You can use another sort). I can limit maxClauseCount to few values (avoid out of memory and better performance). Hope this can help someone. I think it would be a nice feature to implements in lucene. PS: sorry for my poor english. -- Mit freundlichen Grüßen i. A.
