tags in the results list. Gigablast claims to be indexing all "generic" meta tags.
In addition, it can display the meta tags in the results list. Doing this requires
adding commands to the URL of the results list. At the end of the uri, add a
&dt= followed by the word(s) for the meta tags, followed by a colon, and then a
number to represent how many characters from each meta tag should be
displayed. So, for example, adding &dt=keywords+author+generator+description:30
will display the meta tag content for meta keywords, meta author, meta
generator, and meta description tags for any records retrieved. Use a +
between meta tag words. It seems that this "generic" meta tag approach
excludes more complex meta tags like Dublin Core, which use a syntax like
DC.Creator. The dot syntax will not work for the display command, although
Gigablast does index some of the content of these tags."S8
