excludes any terms in a search.

Wild Cards

• Topic is harmful effects of cigarette smoking
• Web sites containing the following words, smoke,
  smoking, smokers, smoked, and smokes, may be
  helpful in your search
• If your search engine allows wildcards, you would
  enter smok

  contained words that started with smok would be
  in your result list.
