You have to reindex everything, the field cannot be converted. Updating single fields is not possible (maybe in future, see wiki).
If you use the field cache (sorting against numeric fields) it is very important to not have any legacy terms in the index, so the best is to start with an empty index. If you do not sort, NumericRangeQuery will simply not hit any documents using another encoding. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -----Original Message----- > From: Siraj Haider [mailto:si...@jobdiva.com] > Sent: Tuesday, October 20, 2009 5:47 PM > To: java-user@lucene.apache.org > Subject: Using NumericField > > We have an index with a number field indexed as String field.
