The ToDo list states:
AltaVista style +/- boolean queries
I thought it was ONLY +/- boolean queries :)

Sorry, I didn't explain myself. This was not about template building.
I'ts about template choosing and MIXING in the same output.
We are also building a directory. We would like to give reviews of products
or services from each site in the directory etc. etc.
When it come to the search engine I'd like to modify the appeareance of
particular urls. If, say, the third url spanned from the search is in the
directory and has a good rating for products, I would have it in the
in a line like: (as with star_patterns)
template_patterns: http://www.thethirdurl.com/ templates/good_prodocts.html
The first 2 urls would appear with standard template and the third site in
the list would be different....
I would also use this to give URLs from our site a totally different look
from other site's pages.

I'km already playing a lot with factors. It's not easy to fine tune them,
Keywords and description are very important to us. Good use of this can
be a real plus for good search results and service. Also its just a few
pages who are spamming that bad. Perhaps it 3 in 100. Problem is that 97
are getting penalized.
Having something to distinguish would be great.
What I proposed is quite verbose but gives more control, information is our
asset, discarding it without notion is an opportunity loss.

well ranking-lower more common words on a global basis o per document ?
In the second case its frequency analisis.
With long documents you would like to weigh frequency against document
which gives you density....
There is another good reason IMHO for this checking. Good sites with
good service will tend to be compliant with good policies. This means that
this checking should spawn better searches.
I haven't looked to htdig source yet, (besides my c++ knowledge is ~0) so
I don't know if what I am proposing is totally out of the current design.
