By default, the search engine locates pages which have all of the words you entered. But you can modify the search behavior in several ways:

1. Phrase search
   To match an exact set of keywords (a "phrase"), use quotes around them.
   Example: "memo lines"
   
   
2. + search
   If you type a + sign before a word, that word must be on the page.
   By default, common words and characters such as "is", "how", "as",and so on... are ignored. If a common word is essential to your search, you can include it by putting a "+" sign in front of it. (Be sure to include a space before the "+" sign.)
   Example: sender +as
   
   
3. - search
   If you type a - sign before a word, that word should not be on the page.
   Example: print -printer
   
   
4. Boolean search
   You can use the boolean operators AND and OR. These operators must be in capital letters.
   Example: (print OR Printer) AND paper
