That's not quite right. The following obsolete meta tags are recognized
by htdig, regardless of what keywords_meta_tag_names is set to:

<META htdig-keywords="blah blah blah">
<META keywords="blah blah blah">

The preferred form is

<META name="foo" content=blah blah blah">

where "foo" is any name listed in keywords_meta_tag_names.

Yes, that's correct. Regardless of which form you use, of the three
forms I've mentioned above, and regardless of the name that you use from
the keywords_meta_tag_names list, the words are all indexed using the
weight defined by keywords_factor.

I think this would be a very useful feature as well. In the 3.2
development code, words in the index are tagged with a code that indicates
where the word was found (i.e. text, title, heading, keywords, etc.),
so that weights can be reassigned dynamically at search time, without
needing to reindex. However, there is still just one tag for keywords.

It would be very useful if there were a number of user-definable tags for
words, for which you could assign different weights. A number of users
had expressed interest in being able to index Dublin Core tags for author,
subject, etc., and limit searches to these tags, so I think there's enough
demand to warrant this. All we need now is a volunteer to implement it.
