Too many results with RegexQuery

Hi, I am using RegexQuery aiming to get a list of records from a regular expression, but in some cases the search returns too many results, and for that my program throws an Exception. How could I customize the query or the searcher to, for example, get just a set of results? Thank you so much!

Missing RegexQuery class

Hi, Does anybody know why at lucene API documentation you can find the package regex and its classes (RegexQuery, RegexTermEnum, SpanRegexQuery...), but they don't exist in the jar (so you can't use them)? Can I find them somewhere? Thank you so much! -- View this message in context: http://w

Searching for partial matches

Hello, I am new to Lucene, and I don't know if it is possible to obtain results providing part of the keyword. For example, if I try to search "in", it should return all matches with "string", "meaning", "trinity"... Am I expecting too much? Thank you so much! -- View this me
