When you enter a phrase in quotation marks, the search engine matches them exactly.
Search Engine Math:
Plus (+) and minus (-) help narrow search results and filter out unwanted listings. 13 13

Boolean logic consists of three operators—AND to combine terms, NOT to exclude terms, and OR to search for similar terms.

Copyright is the exclusive right to make and use literary, musical, or artistic work.
A trademark is similar to a copyright, but relates to visual or commercial images.
If a copyright or patent protection has lapsed on certain material, it is considered public domain and is available for anyone to use. 19 19

20. Web Sites and Intellectual Property Laws (continued)
Citing Internet Resources:
You must give proper credit for information. Claiming someone else’s words as your own is plagiarism.
Respecting Others:
Only publish information about others that is true or you could be sued for libel.
Online Responsibilities:
Behave responsibly online, just as in life. 20 20

21. 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 21

22. 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 22

23. 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. 23 23
