Google 近期也增加了同义词检索功能。
例如：使用：~help 搜索
在结果里，您会发现有Guide、help、tutorials等相似的词出现在结果里，在进行复杂搜索与模糊搜索时引功能将会提供很大的帮助！
August 04, 2003: Big News! New Google Operator
From Google Spokesperson, Nate Tyler:
Today, Google introduced a new advanced search feature that enables users to search not only for a particular keyword, but also for its synonyms. This is accomplished by placing a ~ character directly in front of the keyword in the search box.
For example, to search for browser help as well as browser guides and tutorials users can search for browser ~help. The ~ character was chosen because it's shorthand for approximate and a good way for users to express their wish to expand searches to include synonyms. More information about this feature is available.
This enhancement shows that Google continuies to develop new resources that enable users to refine their searches to find the information they need. I hope you find the ~ operator useful - please take a look and let me know if you have any questions.
