How to search number in text field?

[Floyd Wu]

Hi all,
When using StandardAnalyzer indexing documents, Lucene.Net did not search
for numbers in text fields with numbers.
For example, I have built a index which title is 2009123.
Fire the querystring as "title:2009" returns no records and even if using
title:2009*
There does exist record with title value=2009123;
How can I search this record when my client really want to use 2009 as
keyword for searching?

Thanks

Floyd
