[Zope] Weighing catalog searches per index ?

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

Hello,

Does anybody know of a decent implementation of a scoring algorithm that
does "weighing" of results, presumably based on the indexes used ?

I'd like to explore the possibility of searching the catalog, but giving
results from certain indexes priority over others.

So in the case of the CMF, saying that if search terms are found in the
Title or Descrption, they are more "important" than if they're found
somewhere else and so on ...

I know this is a common concept in more advanced search engines (Such as
Oracle's InterMedia), but I'm wondering if anyone has done something like
this in Zope ...

Thanks,
