Hi All, i used to search 3 Lucene Index store of size 6 GB,10 GB,10 GB of records using MultiReader class.
here is the following code snippet: Directory indexDir2 = FSDirectory.getDirectory(indexSourceDir02,false); IndexReader indexSource2 = IndexReader.open(indexDir2); Directory indexDir3 = FSDirectory.getDirectory(indexSourceDir03,false); IndexReader indexSource3 = IndexReader.open(indexDir3); Directory indexDir4 = FSDirectory.getDirectory(indexSourceDir04,false); IndexReader indexSource4 = IndexReader.open(indexDir4); IndexReader[] readArray = {indexSource2,indexSource3,indexSource4}; //merged reader IndexReader mergedReader = new MultiReader(readArray); IndexSearcher is = new IndexSearcher(mergedReader); QueryParser parser = new QueryParser("contents" ,new StandardAnalyzer()); String searchQuery= new StringBuffer().append(inputNo).append(" AND dateSc:[" ).append(fromDate).append(" TO ").append(toDate).append("]").append(" ").append("AND").append(" ").append(callTyp).toString(); Query callDetailquery = parser.parse(searchQuery); hits = is.search(callDetailquery); it takes 300 MB of RAM for every search and it is very very slow is there any other way to control the Memory and to make search faster.i use SINGLETON to use the IndexSearcher as a one time used object for all the instances. -- View this message in context: http://www.nabble.com/Java-Heap-Space--Out-Of-Memory-Error-tf4376803.html#a12475468 Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
