 Plus (+) and minus (-) help narrow search
results and filter out unwanted listings.

Lesson 28
Summary
In this lesson, you learned:
 You typically create content for the Internet by
publishing it on a Web page and providing links
for navigation. Viewers visit your site and
interact with the information you provide. Web
2.0 technology lets you invite Web page viewers
to contribute information to a site or exchange
information, messages, and files with other
viewers.
21

Lesson 28
Summary (continued)
 When searching online, one of the primary tools you can
use to find information is a search engine. You use a
search engine to search for keywords.
 Keywords describe the information you are trying to
locate and most search engines support keyword
searches. Use double quotation marks around a set of
words for phrase searching.
 Use the plus and minus sign for inclusion and exclusion
of words within a search. Boolean searches use the three
logical operators OR, AND, and NOT.
22

Lesson 28
Summary (continued)
 Many search engines offer advanced search
options that let you filter search results with specific
criteria. Use the * symbol for wildcard searching.
 To evaluate Web sites, consider relevance and
reliability, page layout, validity and bias, writing
style, and coverage.
 Cite any information that you use from the Internet.
The MLA style is widely used for citing electronic
resources.
