Google is different than all of the other ways you can search for legal information, because there isn't another person on the other end who is answering your questions. You have to get your "answers" from the results htat you receive, and fine-tune your search results from there.
The first thing you should is to refine what exactly your question is. If you can do so, get it into one sentence. The example I'll use is "How do I sue somebody in New Jersey?" You may have (actually, you should have) quite a longer description than that, but there's no sense in feeding Google a book.
Given those results, look and see if anything speaks to you. You won't necessarily know what you're looking for, but maybe someone has the same problem that you do (oh, they're trying to sue for a small amount of money and do it themselves, just like me!) or maybe there is a government resource on the topic (like a pro-se kit, such as provided at njcourtsonline.com).
If you find keywords that you think are relevant, but you didn't put them in your original search, re-run the search with them in there. Basically, if you find something that is a "term of art" or means a very specific thing, and that thing is relevant to you, include it in your search. A word about choice of keywords: my experience is that nouns are more often "terms of art" or good keywords, because people use verbs and adjectives more indiscriminately.
Google searching takes patience and time. You'll need to keep looking for things gradually, and I'm sure you'll find them if you keep at it. There are also other resources for the art of google searching; I'm sure that a quick search will bring them up for you. :)
