Subject [jira] [Commented] (LUCENENET-556) Search on several terms returns invalid data
Date Tue, 17 Nov 2015 09:33:10 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15008367#comment-15008367

Simon Svensson commented on LUCENENET-556:
------------------------------------------

We can not answer how Luke works since you we have no clue how you're using it. You've said
that the problem can not be reproduced in a unit test, that means it's an indexing issue.
Perhaps it's just that you have an indexed _non-stored_ integer that matches (since it's 199)
but your code gives you zero since it can not be fetched (since it isn't stored)?

>          Issue Type: Bug
>    Affects Versions: Lucene.Net 3.0.3
>         Environment: Windows 10 x64, .NET 4.5.2

> We have Index on 3 fields:
> map.Key(p => p.ChildId);
> map.Property(p => p.ChildId).NotAnalyzed().Stored();
> map.Property(p => p.Organization).AnalyzeWith(new KeywordAnalyzer()).Stored();
> map.Property(p => p.YearOfRest).AnalyzeWith(new KeywordAnalyzer()).Stored();
> And we make simple query:
> Lucene.Net.Search.IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher(dir);
> BooleanQuery booleanQuery = new BooleanQuery();
> var analyzer = new StandardAnalyzer(Version.LUCENE_30);
> var query = new QueryParser(Lucene.Net.Util.Version.LUCENE_30, "Organization", analyzer).Parse("199");
> var query2 = new QueryParser(Lucene.Net.Util.Version.LUCENE_30, "YearOfRest", analyzer).Parse("1");
> booleanQuery.Add(query , Occur.MUST);
> booleanQuery.Add(query2 , Occur.MUST);
> var doc = searcher.Search(booleanQuery, 20);
> doc has invalid data(docs with organization = 0), we checked query in Luke program, and
everything work fine. Sometimes, program crashes with IndexOutOfRangeException somewhere in
scorer doc has Id over bigger than actual in index.
> Querying on one field works fine.
> Can attach or send index file in 50 Mb
