Here are a few points to keep in mind:

• The case of letters doesn't matter
  All searches are case insensitive. This means you don't have to know whether a word is capitalized or not, or whether it is a title in all caps. For example, searching for "help" will match both "help" and "Help".

• Each word is treated as a prefix
  A word on a Web page will match your search string if it begins with the same letters. Thus, "bread" matches "bread", "breads", "breaded", "breading", and "breadth". (If you check the "match exact words only" checkbox, then the whole word must match your string--that is, "bread" will only match "bread".)

• Words in a phrase must be near one another
  When you enter more than one word to search for, Web pages will be selected only if all the words you enter appear close to one another, typically in the same sentence or paragraph. Notice that this is different from most Web searches, where pages are chosen if the words appear anywhere on a page.

• The order of words in a phrase doesn't matter
  If you enter more than one word, they will match a Web page if the same words appear near one another in any order.

• Common words and short numbers are ignored
  Some words appear so commonly on Web pages that the search function ignores them. In addition, words and numbers shorter than three characters are ignored.
