I have developed a fuzzy search application over a database of books (titles, authors etc) and it works really well. (I use Lucene.Net but read the JavaDocs and forums for java Lucene)
However I've got an interesting use case with "TooManyClauses" and need some help in solving it. My users accept that silly title queries like "m*" are going to return too many results to be useful but they want to combine the wildcard searches with other search terms. For example: Use Case 1 A user wants to search for books by "Charles Dickens" This works fine using a term query and about 500 results are returned Use Case 2 A user wants to search for books by "Charles Dickens" where the title starts with M This throws a TooManyClauses exceptions (or eats a huge amount of RAM) because, I guess, Lucene treats the two as independent queries and M* is expanded across the whole index and not just the books by Charles Dickens. User's don't understand why the Use Case 1 works but Use Case 2 doesn't. Use Case 2 as actually being a more restrictive query and will return better results than Use Case 1. I've thought a bit about how to solve this but none of them seem very elegant or efficient. One solution could be too eliminate one or two character wildcards from the inital search and then loop through the results doing a String.contains or something horrible. Another solution could be through clever use of the QueryFilter classes but I don't quite understand how they work yet.
