Subject [jira] Commented: (NUTCH-585) [PARSE-HTML plugin] Block certain parts of HTML code from being indexed
Date Sun, 02 Dec 2007 17:26:43 GMT

Otis Gospodnetic commented on NUTCH-585:
----------------------------------------

A more general solution is needed.  This solution should not rely on apriori marked-up content
as in your example, but should automatically recognize things like footers, sidebars, repeating
navigation and other elements, etc.

I am sure there are PhD thesis out there on this topic...

> We are using nutch to index our own web sites; we would like not to index certain parts
of our pages, because we know they are not relevant (for instance, there are several links
to change the background color) and generate spurious matches.
> We have modified the plugin so that it ignores HTML code between certain HTML comments,
like
> <!-- START-IGNORE -->
> ... ignored part ...
> <!-- STOP-IGNORE -->
> We feel this might be useful to someone else, maybe factorizing the comment strings as
constants in the configuration files (say parser.html.ignore.start and parser.html.ignore.stop
in nutch-site.xml).
> We are almost ready to contribute our code snippet.  Looking forward for any expression
of  interest - or for an explanation why waht we are doing is plain wrong!
