Searching with Keywords

When you search a book’s index for a particular topic, you have to think for a moment, predict which term or terms may be used to identify the topic, and then start looking. Doing a computer search involves a similar process. Follow these steps:

    1. Define your topic. Precisely stated topics yield focused results. Too broad: Greek drama
More Precise: Women in Greek drama; themes of Greek drama

      Note: Guiding research questions (see page 364) can serve as topics in a computer search. Example: What preparations must I make to travel outside the U.S.?

    2. Make a list of keywords. Break your topic into parts or terms. Each term is a keyword or key phrase. Also list alternative words or phrases for your search.
    3. Examples: travel, preparations, outside the U.S. Alternatives: foreign travel, travel planning, visiting overseas, world travel
  1. Use Boolean operators. Special operators such as the words and, or, and not; quotation marks; and +’s and –’s help a search site process your request. (Check advanced search options for operators.) Boolean operators work as follows:

Operator

Examples

Graphic Representations

and or +

travel and foreign travel + foreign

Files with both “foreign” and “travel” separately

not or

travel not foreign travel foreign

Files with “travel” but without “foreign”

“ ”

foreign travel

Files with the exact phrase “foreign travel”

or

travel or foreign

Files with “travel” or “foreign” or both

* (or other “wild card”)

travel*

Files with “travel” or “traveled” or “traveler” or “traveling” (and so on)

 
  1. Evaluate your results. If your keywords are well thought out and your search program has a complete database, you’ll receive good results. If your results are disappointing, however, you’ll need to either revise your keywords or use a different search program (or both) and try again.

Your Turn Review your list of keywords from page 368. Use Boolean operators to search with them.
