You’ve heard of Google. You’ve no doubt heard of Yahoo, too. But do you really know how to use them? If you’re frustrated by search engines that give you unrelated responses ... if you’re spending too much time just looking for online resources ... , read on to learn a few useful online search strategies, which will help you find what you’re looking for and save you precious online time.
Before you type a search string in the search box of your favorite search engine, take a few minutes to come up with a precise description of what you’re looking for. Let’s say that you’re interested in information about animals of the ocean. If you type that phrase into Google’s search box, for example, you’ll get close to 19 million hits. Put quotation marks (" ") around the phrase--"animals of the ocean" -- and you’ll get just 531 hits: Why? Because the quotation marks direct the search engine to find only pages that contain that exact phrase. Without the quotes, the search engine will find every page containing the word animals and every page containing the word ocean. (Most search engines ignore such words as "of" and "the". ) So whenever you have more than one word in your search string, use quotes!
Let’s say you’re looking for "videos of humpback whales in the North Atlantic." Type that exact phrase into Google’s search box ( sometimes a good way to start a search!) and you’ll get 0 hits. A search for whales turns up 12.8 million hits. A search for "humpback whales" narrows it to 660,000 hits. Still too many to work with!
Now, try the plus (+) sign. The search term "humpback whales" +videos yields 41,100 hits. The plus (+) sign directs the search engine to find pages that have all the words or phrases found in the search string. Want still fewer hits? Type in "humpback whales" + videos + "North Atlantic"; the number of hits is reduced to just 746.
The minus (-) sign also comes in handy for narrowing a search. The search term "humpback whales" + videos + "North Atlantic" -Pacific returns 339 hits. The minus sign (-) directs the search engine to leave out any pages that have the designated word or phrase. It limits your search to a more precise collection of pages.
When you have more than one word in your search string, the use of quotation marks can help ______.
选项
A、narrow your search
B、locate the exact information you want
C、get as many hits as possible
D、find all pages containing each of the words in the search string
