[jira] Updated: (LUCENENET-338) Serialized queries function unreliably
[ https://issues.apache.org/jira/browse/LUCENENET-338?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Digy updated LUCENENET-338: --- Attachment: Term.patch Serialized queries function unreliably -- Key: LUCENENET-338 URL: https://issues.apache.org/jira/browse/LUCENENET-338 Project: Lucene.Net Issue Type: Bug Environment: Current trunk, standard .NET environment, Visual Studio 2008. Reporter: Moray McConnachie Attachments: Term.patch, Term.patch I've just tried slotting in current trunk in place of 2.3.1 we were using previously. Everything appears to compile and work OK, but the results are not correct when we introduce query serialization. Executing a simple BooleanQuery: +titling:Russia Results returned from query when not serialised: 3878 (correct) Results returned when query serialised deserialized and run with same Searcher: 3879 Results returned when query serialised deserialized and run with new Searcher: 3 (!) Last time we had an issue with serialized queries and filed a bug report (https://issues.apache.org/jira/browse/LUCENENET-170), it was an issue with the serialization of Parameter on which Occur depends, but Parameter looks still to have the patch in as far as I can tell. *Test code* string IndexPath=@C:\SourceSafeWork\OxanOxweb\LuceneAndSearch\TEST\LuceneIndexWithFullTextSince2004; //setup first query BooleanQuery lucQuery = new BooleanQuery(); lucQuery.Add(new BooleanClause(new TermQuery(new Lucene.Net.Index.Term(titling,russia)),BooleanClause.Occur.MUST)); //serialize and deserialize BinaryFormatter bf = new BinaryFormatter(); System.IO.MemoryStream ms = new System.IO.MemoryStream(); bf.Serialize(ms, lucQuery); ms.Seek(0, System.IO.SeekOrigin.Begin); Query lucQuery2 = (Query)bf.Deserialize(ms); ms.Close(); //get hit counts for 2 searches IndexSearcher searcher = new IndexSearcher(); int hitCount = searcher.Search(lucQuery, 20).totalHits; //3878 hits //bizarrely if I do not close the searcher and reopen the hit count is only 1 different i.e. 3879 searcher.Close(); searcher = new IndexSearcher(@IndexPath); int hitCount2 = searcher.Search(lucQuery2, 20).totalHits; //3 hits if (hitCount != hitCount2) MessageBox.Show(Error in serialisation - different hit count); -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
