Thx Uwe, after sleeping over the problem... The solution just hit me ;) I index a double for the Numeric field but my Sortfield was setup as a float. (Maybe this is something for a FAQ for NumericFields)
Thx Uwe -----Ursprüngliche Nachricht----- Von: Uwe Schindler [mailto:u...@thetaphi.de] Gesendet: Dienstag, 26.

The problem is that even if no document contains the old field encoding anymore, it could still be leftover terms in terms index. So the FieldCache code loads the terms (even if no longer documents are attached) and tries to parse it. So if it was before a different field type like a conventional plain text encoded numeric, the parsing of those old terms fails. You should reindex the whole stuff or at least try to optimize the index to get rid of deleted documents and the terms. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Uwe Goetzke [mailto:uwe.goet...@veenion.de] > Sent: Monday, October 25, 2010 9:43 PM > To: java-user@lucene.apache.org > Subject: Problem with sorting on NumericFields > > I got stuck on a problem using NumericFields using with lucene 2.9.3 > > > > I add values to the document by > > doc.add(new NumericField("minprice").setDoubleValue(net_price)); > > > > If I want to search with a sorter for this field, I get this error: > > > > java.lang.NumberFormatException: Invalid shift value in prefixCoded string (is > encoded value really an INT?) > > at > org.apache.lucene.util.NumericUtils.prefixCodedToInt(NumericUtils.java:2 > 33) > > at > org.apache.lucene.search.FieldCache$8.parseFloat(FieldCache.java:256) > > at > org.apache.lucene.search.FieldCacheImpl$FloatCache.createValue(FieldCach > eImpl.java:514) > > at > org.apache.lucene.search.FieldCacheImpl$Cache.get(FieldCacheImpl.java:22 > 4) > > at > org.apache.lucene.search.FieldCacheImpl.getFloats(FieldCacheImpl.java:48 > 7) > > at > org.apache.lucene.search.FieldCacheImpl$FloatCache.createValue(FieldCach > eImpl.java:504) > > at > org.apache.lucene.search.FieldCacheImpl$Cache.get(FieldCacheImpl.java:22 > 4) > > at > org.apache.lucene.search.FieldCacheImpl.getFloats(FieldCacheImpl.java:48 > 7) > > at > org.apache.lucene.search.FieldComparator$FloatComparator.setNextReader(F > ieldComparator.java:269) > > at > org.apache.lucene.search.TopFieldCollector$MultiComparatorNonScoringColl > ector.setNextReader(TopFieldCollector.java:435) > > at > org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:257) > > at > org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:240) > > at > org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:181) > > at > org.apache.lucene.search.Searcher.search(Searcher.java:90) > > > > The Sort field as seen by the debugger: > > * sort_fields = {org.apache.lucene.search.sortfield...@9010} > * [0] = {org.apache.lucene.search.sortfi...@9011}"!" > * field = {java.lang.str...@8642}"minprice" > * type = 5 > * locale = null > * reverse = true > * factory = null > * parser = null > * comparatorSource = null > * useLegacy = false > > I run out of ideas what might go wrong.
