When Venn diagram circles overlap and the part of one circle that does not overlap the other one represents search results, one set was excluded from results.

____ diagrams can help you decide which Boolean operators to use in a search strategy.

Although a metasearch engine can do many parallel searches, it actually accesses less of the Web than single search engines.

The ____ Google search operator allows you to locate pages based on the keywords used to link to them from other pages.

The operator that the engine automatically uses is called the ____________________ operator.

Whenever you connect keywords in your search with OR, you are commanding the search engine to find both of the keywords together on a Web page.

All major search engines use standard operators for advanced search.

Use the Boolean operator ____ when trying to broaden a search.

A(n) ____________________ is a program that a search engine uses to screen out Web pages.

Boolean operators tell a search engine how to interpret your complex searches.

If you use ____________________ in your search, the keyword that follows will not appear on any of the Web pages returned.

The ____________________ sign is useful to prevent a search engine from ignoring a stop word.

You are a reporter for your college newspaper and planning some advance columns for a weekly Internet column. You know it would be helpful for your readers to understand what's going on in advanced searches with Boolean logic. It seems too daunting to try to cover in one column, so you decide to start by making notes about what you want to cover in several columns. Record the information you would cover in a column about what the Boolean operators AND, OR, and NOT actually do when you use them.

Describe the use of the Boolean operator AND, including how and why it is used in complex search queries and how its use changes search results. Also include a drawing of a Venn diagram illustrating a sample search using AND.

The circles in Venn diagrams represent ____.

Describe the use of the Boolean operator OR, including how and why it is used in complex search queries and how its use changes search results. Also include a drawing of a Venn diagram illustrating a sample search using OR.
