Hi,

We have implemented a lucene search like this:

registry =3D LocateRegistry=2EgetRegistry(RMIAddress, RMIPort);
searchables =3D new Searchable[] { (Searchable) registry=
=2Elookup(RMIIndexName)};
queryParser =3D new QueryParser(defaultField, new StandardAnalyzer());
Query query =3D queryParser=2Eparse(queryString); // queryString is=
 something the user specified, like hello*
Searcher searcher =3D new MultiSearcher(searchables);
hits =3D searcher=2Esearch(query);

There is furthermore a field in the index called documenttype=2E

The problem is this, when searching for "documenttype:Specifikation" I get=
 the expected results, but when searching for "documenttype:blankett/mall"=
 I get none=2E I can show, using a class simply displaying the index=
 contents, that there is actually a field called documenttype containing=
 the value "blankett/mall" in several cases=2E

I first suspected the "/"-sign to be the cause of the problem, but=
 searching for "documenttype:blankett/ma*" actually returns the expected=
 result=2E

I understand that there are several different query types, but should not=
 the queryParser create a correct query for me? I am quite stuck here and=
 would truly appreciate any help possible!=0D

Best regards,
Bj=F6rn Lilja
