1.使用双引号进行精确查找 如果查找的是一个词组或多个汉字,最好的办法就是将它们用双引号括起来,这样得到的结果最少、最精确。例如在搜索引擎的 Search(查询)框中输入“search engine”,这会比输入searchengine得到更少、更好的结果。 如果按上述方法查不到任何结果,可以去掉双引号试试。 2.使用加减号限定查找 很多搜索引擎都支持在搜索词前冠以加号(+)限定搜索结果中必须包含的词汇,用减号(-)限定搜索结果不能包含的词汇。 1. Use double quotes for exact Find If you find a phrase or multiple Chinese characters, the best way is to enclose them in double quotes, this results in the least, the most accurate. For example, entering “search engine” in the search engine’s search box will result in fewer and better results than entering searchengine. If you can not find any result by the above method, you can remove the double quotes to try. 2. Search with Addition and Minus Limits Many search engines support the inclusion of a plus sign (+) in a search term to limit the words that must be included in the search results and a minus sign (-) to limit the words that the search results can not contain.
