.sN (separate norms files) and NO_NORMS

Hi, I recently run the FieldNormModifier (see http://issues.apache.org/jira/browse/LUCENE-741 ) on 8 fields that I wanted to turn into NO_NORMS fields. I run this on several optimized .cfs indices. Afterwards I noticed that *some* (but not all!) indices contained 8 .sN (where N is a number)

Re: opening an IndexWriter for an exisiting index causing lock exception

Thanks Mike, you are right. There was a really bad test method that didn't clean up after itself. Thanks for the heads up. This was not a Lucene problem, it was just me not going through all of the unit test methods. On 1/8/07, Michael McCandless <[EMAIL PROTECTED]> wrote: S Edirisinghe wrote:

Re: Remote Searcher performance and Document retrieval

No, I haven't compared it to a local index, but when working on other projects in the past I've always seen that "chatty" remote access can really hurt performance, and that batching up multiple calls into a single remote access saves a lot of time. Alex -- View this message in context: http:/

Remote Searcher performance and Document retrieval

I have a question about the performance of the following Lucene setup: I have a MultiSearcher that contains 3 RemoteSearchables that point to IndexSearchables on 3 different boxes, and each index contains about 20,000 docs. When an end user runs a search, results are displayed with 20 hits per pa

Well, my testing mostly consisted of capacity testing. I'm using XmlRpc as my communication mechanism and simply fired up a (configurable) number of threads to pound my search service with semi-random queries and measured the response time. Your results may vary depending on how your index is stru
