[Amanda Xu <AXu@epnet.com>]

Do you expect the end-user to understand 
term weighting techniques as well as the 
structure of an XML document?

I think you are suggesting that wighting and selection
should be done at query time instead of at index time.
That is a design tradeoff for the search engine. But the
detailed weighting and selection belong *somewhere* in
the search engine rather than in every single document.

I can imagine a system where each document had indexing
hints scattered throughout the structure, but I can't
imagine anyone having the time or knowledge to do a good
job with all that markup. We have enough trouble getting
people to replace "Untitled Document" in the <title> element
in HTML.
