SECTION 3: USING SEARCH ENGINES EFFECTIVELY

BOOLEAN LOGIC: AND/OR

OR is the same as the "3. with at least one of the words" option. Using an OR will find any of the search terms.

Remember that using an OR will find the search terms in any order, anywhere on the Web site unless you use other ADVANCED FEATURES to specify where in the Web site the search terms appear.

OR Examples:

pain control or pain management	Finds Web sites that includes either of the phrases "pain control" or "pain management". Using the OR is helpful if you are not sure exactly how a Web site will be saying something, or if there is more than one way to express a concept. In this case, you will find Web sites that say either pain "control" or "management" Some search engines would require you to put "quotes" around the phrases. Always check the Advanced Search options to find out for sure whether the quotes are required.
aids drugs or aids therapy or aids treatment	Finds Web sites that includes either phrase.
AZT or Retrovir or zidovudine	Finds Web sites that includes any of the terms "AZT" or "Retrovir" or "zidovudine". Again, using the OR is useful if you do not know exactly which word would be used on a Web site.
