Can anyone elaborate further on numerical searches and relevance in
nutch?  For example, if we had a set of pages, each of which detailed a
certain product and that contained a price, would it then be possible to
search for a range of prices.  Would it also be possible to order
relevance by numerical value instead of string-based relevance, e.g if I
searched for 200 would a page containing 210 be more relevant than a
page that contains, say 2000.

Any suggestions, ideas would be welcome.  I realise that lucene is a
text-based index and search component, but I'd be interested if anyone
had done any work or research into numerical relevance.

Cheers
Aled
