------------------------------------

Hi Bojan Tomic,

Thanks for your contribution. I have tested your plugin and it worked well. 
But, the creation of a new field (filtered_content) in MySQL haven't worked, 
the field became NULL on MySQL. I have tried to change the 
"gora-mysql-mapping.xml" and add the new field, but when i used the inject 
command, i have got "org.apache.gora.util.GoraException: java.io.IOException: 
java.lang.NullPointerException". Do I have to do an extra configuration? How 
can I make it work out?

Thank you.

> 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!
