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...
> [PARSE-HTML plugin] Block certain parts of HTML code from being indexed
> -----------------------------------------------------------------------
>
> Key: NUTCH-585
> URL: https://issues.apache.org/jira/browse/NUTCH-585
> Project: Nutch
> Issue Type: Improvement
> Affects Versions: 0.9.0
> Environment: All operating systems
> Reporter: Andrea Spinelli
> Priority: Minor
>
> 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!
