By the way: This is documented: http://hudson.zones.apache.org/hudson/job/Lucene-trunk/javadoc/core/org/apac he/lucene/document/NumericField.html
NOTE: This class is only used during indexing. When retrieving the stored field value from a Document instance after search, you will get a conventional Fieldable instance where the numeric values are returned as Strings (according to toString(value) of the used data type). (this o.a.l.document.Fieldable is always a o.a.l.document.Field) ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Uwe Schindler [mailto:u...@thetaphi.de] > Sent: Friday, September 11, 2009 10:38 PM > To: java-dev@lucene.apache.org > Subject: RE: NumericRange Field and LuceneUtils? > > Hallo Daniel, > > I am not really sure what you are talking about (what is LuceneUtils?). > > To your question about NumericField: NumericField is only used for > indexing. > If you also store the field to retrieve it from the index e.g. with search > results, NumericField creates a stored Field containing the number as a > conventional string (the special trie encoding is only used for *indexing* > not *storing*).
