Searching behaviour with content containing decimal points
I have content such as "E71.0" and when I enter a search query of "E71" I
would like it to match that document. At the moment though it only matches
that document if I enter "E71*" or "E71.0".
What's the trick to getting such a query to match this document? I am using
StandardAnalyzer and QueryParser at the moment in Lucene Java 3.2.
Thanks,

I have included the previous post as I realise not everyone accesses this
content via the web.

You have to do some normalizing here, and I don't think there's
anything available out of the box, so you'll probably have to roll
your own filter that does the normalization for this field.
Be a little cautious, though. Your example, while fine itself, may not
generalize. Your rule for normalization might be "remove all non
alphanum characters and drop trailing zeros". But if applied to,
say, part numbers does it still make sense? Does your user base
expect a part number (or something) like 123000 to fail to match
1230?
Anyway, you'll probably be making your own custom Analyzer
for this by chaining together, say, WhiteSpaceTokenizer with
your custom Filter.

Actually I have this issue too. I've played around with various analyzers,
and I would expect the WhitespaceAnalyzer to work (at least) but it does
not.

Can anyone help me with this? Do you require further information? This has
become a serious issue for us.
