Unfortunately Tika currently has the same issue of not inserting
spaces between menu list items, which gives you these types of
concatenated results.
It's a trivial patch, I just need a few minutes of spare time :(

Hi
I would suggest you to try the tika parser if you are not using it
now. It
might give you better parsed HTML. Next - if you want exclude some
parts of
text from HTML than you must re-write html parser and adopt it to your
needs.
To reduce relevancy of your page - you may play with boost values
which are
are configured in the nutch-site.xml. But they will apply to every
crowled
page and so if you want to apply it to only one(serveral) page then
you
might want to look at this patch.

I have an old page on my site that Nutch is fetching. The results
in the
Nutch web app look like this:

The big block of text there are the option values in a drop down
menu.
What's weird is that this page has 2 drop down menus, but Nutch
only grabs
one of them and does this kind of thing. It's an ancient page and
unfortunately each option value is actually a URL, which I'm
guessing is
why
Nutch is indexing the values, but it's odd that it only does it for
one
menu
and not the other.
Another problem is that in the web app, this wall of text doesn't
wrap so
it
completely messes up any formatting to our custom search application.
Lastly, this page is the first hit in the list of results for a
search on
the term "map" entirely due to the page being called "sitemap". I
could
probably fix this easy by just calling it something else, but I
would like
to know the best way to handle something like this in Nutch.
First, how do I get nutch to stop pulling all the menu option
values into
the results list. Second, how do I reduce the relevancy of this page
without
changing the page itself?
