Right. And that is why I am asking. Should the GUI
give clues to the filtering? If yes, it gets harder
to use. If no, its reliability vis a vis a common
mental model is lowered.
One should be sure what those Google numbers are
saying. One should know about the phrase trade.
One should understand blogging keiretsu. One should
be able to set a search based on the credentials
of the sources. One should be able to pick the
types of credentials, not let the bot do that.
Amplified acceptance of unverified assumptions
is the very essence of robot wisdom. I am
wondering about the viability of subscription
search engines that contract for the quality
of their results.

Most modern search engines give greater weight to a term the more
infrequent it is in the corpus. Most also weight terms according to
where and how often they appear in the source document, and some also
recognize when adjacent words in the query constitute a noun phrase.
What google does is anyone's guess.
