searching/filtering by field's value length

2011-07-12 Thread Federico Schroder
Hello, I need some help doing a search. Say I have a really simple document structure, just 1 field, labeled name. I need to retrieve all the names whose length is more or less than a specified value. By length I mean String.length(). A range filter seems close in concept, but I couldn't find a goo

Hi, I am running some AutomatonQueries and see caching effects happening, that I can't seem to get rid of. E.g. an AutomatonQuery takes Run 1: 3000 ms Run 2 and all subsequent runs: 250 ms The IndexSearcher is closed after every full query circle (and opened via open(Directory), so the Index

Wildcard queries don't use the analyzer, as the analyzer may also remove the "*". To work around this, there is an AnalyzingQueryParser in contrib, but be aware, that it may not always work as expected. - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@the

Re: Memory leak with Lucene Search ?

2011-07-12 Thread Ian Lea
Lucene does not cache results. Operating systems do cache things and on unix anyway (no idea about windows) some speedups over time can reasonably be attributed to disk caching by the OS. Have you profiled your app to find out exactly what is using the memory? Do you just use the one searcher or

If I've read your example correctly it appears that at indexing your analyzer is converting "bloom's" to "bloom" but not at search time. Which implies that you aren't using the same analyzer in both cases. -- Ian. On Mon, Jul 11, 2011 at 4:19 PM, jm wrote: > *Hi,* > * > * > *My env is jdk1.6 a
