> 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");
