Refining the search

The search engines allow the user to choose whether to search for the exact typed phrase , all the words in the phrase , any of the words in a phrase , and so on. However , the search engines do not provide such options . In this case , the user can define the search by adding one or more words or symbols to the search topic.

• AND : It is used to search for two or more terms on the same page . Type the word AND between the terms ( for example , poverty AND crime ) or put a plus sign right before the second term (example : poverty+crime).
• OR : It is used to search for either of two (or more) terms on the same page.Type the word OR between the terms (for example , college OR university).
• NOT : It is used to search for pages that include the first term but not the second. Type the words NOT between the terms (for example , cats NOT dogs ) or put a minus sign right before the second term (for example,cat-dogs).
• "" : Double quotes are used to search for an exact phrase.For example , "desktop wallpapers ".
• () : Parenthesis are used to group parts of the search phrase.For example , type desktop AND (themes OR wallpapers ). This returns pages with the words desktop and themes or both the words themes and wallpapers.
• * : Asterisk is used to search for various forms of a word . For example , prior * returns pages with the words prior , prioritise , priority and so on.
