Hi
I currently use NumberTools.longToString() to add integer fields to an
index and allow range searching, then when searching I then preprocess
the query (using regular expressions) and convert integer fields to
NumberTools.longToString before it is parsed by the QueryParser, then
when I return the results I use NumberTools.stringToLong(), so my
implementation is flaky. Now I'm using Lucene 2.9 I thought Id use
NumericField and hoped I could remove the preprocessing instead but I'm
really not clear what I do on the indexing and searching side. I've even
just bought the MEAP version of Lucene Action 2nd Edition and it doesn't
even get a mention (nor does NumberTools for that matter it just
mentions padding numbers with zeroes).
So please anyone got a simple example of how to add a numeric field to
an index, and what has to be done on the search side, assuming receiving
a text string that gets parsed by the QueryParser
thanks Paul
