[Zope] ZCatalog: TextIndex and numbers

Hello, I've a TextIndex on title (Zope 2.5.0). When the title has a value "Restoration Discretionary Programs--Sections 1135, 204, and 206" The index has the value ('restoration', 'and', 'programssections', 'discretionary') As you can see 1135, 204, 206 are not in the index. Is there a quick way to get ZCatalog to consider all words for indexing? Thanks -vsb http://vsbabu.org/
