[MacPerl-WebCGI] Relevancy Rankings

[Richard Gordon <maccgi@bellsouth.net>]

<x-flowed>I'm working on a web site search engine that seems to run okay, but 
I'm having trouble figuring out how to order the results by 
relevancy. Does anyone know how this is done by the commercial 
portals?

It would be easy enough to take the search string and count the 
number of times that it appears in a given document, but this gets 
fuzzy when you are dealing with "or" searches. It also seems to me 
that a weighting scheme that went beyond a raw count of occurrences 
would be entirely arbitrary, but maybe that's true of weighting 
schemes in general.

Anyway, suggestions are welcome. Thanks.
