term boosting has no effect with span queries ?

Hi, I'm trying to boost the score of documents containing some specific terms using the setBoost() method of the class SpanTermQuery (actually inherited from the class Query) but this seems to have no effect on the hits scores. Checking the way the scores are computed (by calling the explain

Real time indexing with RAMDirectory

Hi all, Is it possible, with the RAMDirectory (or another Directory), to flush informations after each Document indexing ? I tried this but this flush appears to be able to be made after 2 indexing at best. What do you think about it ? I forgot a configuration ? Thanks, Mickaël

Strange results using QueryParser (?)

Hi, We have implemented a lucene search like this: registry = LocateRegistry.getRegistry(RMIAddress, RMIPort); searchables = new Searchable[] { (Searchable) registry.lookup(RMIIndexName)}; queryParser = new QueryParser(defaultField, new StandardAnalyzer()); Query query =

only getting Hits with score = threshold

Hi, i'm trying to collect Documents whose (normalized) score is greater than a given threshold. But i don't know what is the smartest way to do so :) Do i have to subclass (Index)Searcher and override search(Query query, Filter filter, final int nDocs) to achieve this? Kai Gülzau

Re: Real time indexing with RAMDirectory

Hi Mickaël, Have you tried using minMergeDocs=1 ? Will that do what you want? Otis --- Rifflard Mickaël [EMAIL PROTECTED] wrote: Hi all, Is it possible, with the RAMDirectory (or another Directory), to flush informations after each Document indexing ? I tried this but this flush appears

Re: Strange results using QueryParser (?)

Hi, My guess is that the analyzer you use for indexing keeps the / (or perhaps documenttype is a Keyword field, while the StandardAnalyzer and QueryParser combination remove the / from the query string. Wildcards work because they are not analyzed:

Re: only getting Hits with score = threshold

Hi Kai, You could use HitCollector for this: http://lucene.apache.org/java/docs/api/org/apache/lucene/search/HitCollector.html Here are some bits about HitCollector: http://www.lucenebook.com/search?query=hitcollector+score A custom HitCollector comes with the book, and you can download the

Re: Indexing in multi-threaded environment

Chris Lamprecht wrote: I've done exactly what you describe, using N threads where N is the number of processors on the machine, plus one more thread that writes to the file system index (since that is I/O-bound anyway). Since most of the CPU time is tokenizing/stemming/etc, the method works well.

Re: expert question: concurrent, asynchronous batch updates and real-time reads on very large, heavily used index

Once an IndexReader is opened on an index, it's view of that index never changes. Reuse the same IndexReader for all query requests and ony reopen it after you do your optimize. -Yonik - To unsubscribe, e-mail: [EMAIL
