Hi your task is clear but solution is not simple. That is why there are so many companies which are competing for users and try to show them relevant results.
Nutch is not cleaver enough to sort out if a page an opinion or just an advertisement. So you MUST yourself to teach it. First of all you need to find out what distinguishes opinions from other pages. It might be special structure, special tag or key word .... Next you must rewrite HTML parser (indexer) and add necessary logic to filter opinions form other pages. so this's basically what you should do.
