Hej hej, i have a question regarding lucenes memory usage when launching a query. When i execute my query lucene eats up over 1gig of heap-memory even when my result-set is only a single hit. I found out that this is due to the "ensureIndexIsRead()" method-call in the "TermInfosReader" class, which iterates over all Terms found in the index and saves them (including all value-strings) in a Term-Array. Is it possible to not read all that stuff into memory at all?
Im doing the query like in the following pseudo-code: ------------------------------------------------------------------------ TopScoreDocCollector collector = new TopScoreDocCollector(100000); QueryParser parser= new QueryParser(field, new WhitespaceAnalyzer() ); Directory fsDir = new FSDirectory(indexDir, null); IndexSearcher is = new IndexSearcher(fsdir); Query query = parser.parse(q); is.search(query, collector); ScoreDoc[] hits = collector.topDocs(); ....... < iterate over hits and print results > Thanks in advance Benedikt --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
