Keyword Search


by Barbara J. Feldman on July 17, 2002

After you’ve mastered the basics of entering keywords into search engines, the next step in refining your skills is adding the math operators “+” and “-” to your repertoire. The plus symbol in front of a search term means the results must always include that keyword. The minus is used for words you never want to appear. For example use “+rockets -houston” to search for rockets that do not play basketball; and “+rockets +models” to search for information on model rockets.
