Sites may often change their organization and page titles but domain names usually remain unchanged. Once at the site's home page you can often locate the information you need. On many search engines, this will help distinguish proper names from similar words. Know the search engine's default search operator. This can produce very different results.
Some search engines are sensitive to word order.
Put your most important search term first. Reformulate your search using different terms or try a different search engine. Understand that only text gets indexed. Search engines do not index graphical text or text contained in images. Frequently web designers only put the name of their site in a company logo or image at the top of the page.
