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

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. wunder -- Walter R.
