1.
Which search syntax would give you the exact URL if you were looking for a Web site for Oprah Winfrey?
Please select the best answer.
A.
+Oprah+Winfrey using Excite
B.
u: oprah winfrey using Yahoo
C.
"Oprah Winfrey" using Alta Vista
D.
Oprah AND Winfrey using Lycos
The correct answer is B.
Answer B is correct because the operative u: in Yahoo restricts searches to document URLs only. It is the only choice given here with that exclusivity. Thus, Answers A, C, and D can be excluded since although they would eventually yield the correct URL, they would find all documents containing the specified words not just the URL. NOTE: Check the advanced search option for all engines and directories to find which operator each uses to restrict a search to only a URL.
2.
