Search Tips

To search for a document, type a few descriptive words in the search box, and press the Enter key or click the search button. Google produces a results page with a list of documents and web pages that are related to your search terms, with the most relevant search results appearing at the top of the page. By default, Google returns only pages that include all of your search terms. So to broaden or restrict the search, include fewer or more terms. You do not need to include “and” between the terms.

Google uses sophisticated text-matching techniques to find pages that are both important and relevant to your search. For instance, Google analyzes not only the candidate page, but also the pages that link to it, too. Google also prefers pages in which your query terms are near each other. Every search result lists one or more snippets, or excerpts from the document, to display the search terms in context. In the snippet, your search terms are displayed in bold text so that you can quickly determine if that result is from a page or document you want to visit.
