Re: Empty search

If you are refering to QueryParser, and if you mean that you want Lucene to *find everything* when you actually say *search for nothing*, you could easily extend current Queryparser to suit your needs: public class MyQueryParser extends QueryParser { public MyQueryParser(String f, Analy

I recognize that error message ;) You're using AnalyzingQueryParser - yes? These are imo the two most obvious options: 1. Revert to standard QueryParser - it won't analyze prefix- and

Re: QueryParser syntax French Operator

Wouldn't the easiest fix be to just alter the users query string before passing it to queryparser (moving the semantics of your search app outside of lucene)? Something like: str.replaceAll(" ET ", " AND ").replaceAll(" OU ", " OR ").replaceAll(" SAUF ", " NOT ") Citerar Mark Miller <[EMAIL PROT

Do not close the searcher until you are done with the Hits object. See the javadocs for Searchable.close() http://lucene.apache.org/java/docs/api/org/apache/lucene/search/Searchable.html#close() /Ronnie Huinan wrote: Hi, I'm having a weird problem: I created an index using IndexWriter. Then

Re: QueryParser returns all documents

You could define your own query syntax (for example an empty string) for a query matching all docs, examine the query string before passing it to QueryParser, and instead create a MatchAllDocsQuery when a you have a match. http://lucene.apache.org/java/docs/api/org/apache/lucene/search/MatchAll

Re: Lucene/Tomcat Memory Leak Issue

How do you index your documents? Are you releasing old resources? Can you use a profiler to see referenced objects? I've experienced the same problem when indexing xml files which were parsed with xalan, and the memory leak in that case was in xalan. Switching to saxon solved the problems for us.

Re: [ANN] Lucene "Did You Mean" article on java.net

Nice article! And for those interested in the different "did you mean" techniques can also look at my simple implementation using the first approach mentioned in the article, minimum edit distance, along with document frequency. This implementation can easily be applied over an existing index. ht
