Most search engines search the headings, hidden titles and, in some cases, the text of web pages.
Knowing what words to search for can sometimes be challenging. In many cases entering search terms that are too general will locate thousands of web documents making it difficult to know which are the most useful. If you are at home and cannot find what you need, call your local library . Librarians are skilled information searchers. And, as strange as it seems in this technological age, not all information is on the Internet, you might be looking for information that is already easily accessible in a book or another online service to which the library subscribes.
