使用Google搜索問題是程序員的必備技能，今天看到了一個帖子專門講了十個Google搜索技巧，這里分享一下：

（文中英文也不難，我就不翻譯了）

1/ Use quotes to force an exact-match search: "what is javascript"

2/ AND operator will return only results related to both terms: html AND css

3/ You can use the OR operator to get the results related to one of the search terms (javascript OR python) free course

4. The "-" operator will exclude results that contain a term or phrase: javascript -css

5/ You can use the (*) wildcards as placeholders, which will be replaced by any word or phrase. "how to start * in 6 months"

6/ Search inside a single website: site:http://freecodecamp.org

7/ You can also use a very useful feature that helps to find a specific file type. Super useful! filetype:pdf learn css

8/ Search for a range of numbers: ecmascript 2016..2018

9/ Use the `before` operator to return only results before a given date javascript before:2020

10/ Use the `after` operator to return only results after a given date web development after:2020
