To retrieve only documents that match the term, but not those that match the lemmas, enclose the term in double quotes.

要查询只与这个词汇相匹配而不与词元相匹配的文档，需要给这个词汇加上双引号。

youdao

Note that the brace expansion of the file path, not the full remote path expression, has been enclosed in double quotes.

请注意，文件路径中展开的大括号（不是完整的远程路径表达式）已用双引号括上。

What benefit does this provide? Mainly, that the content inside the double quotes is not parsed, which provides you with more flexibility.

其优点主要在于，双引号中的内容不会被解析，这样便有了更大的灵活性。

youdao

So if I want to use a string as we'll call it which is a word or phrase generally, they always go between double quotes, David hence the quotes around David, and they are double quotes not single quotes intentionally.

当我们要表示单词啊，词组啊，句子啊等等这样的东西时,就会用到字符串，它们位于双引号之间，也就是这里双引号之间的，是双引号，不是单引号哦。

Now I'm putting count in double quotes, not to make it a string, but to say, this is count generically. It could be counting one by one through the integers, it could also be taking a collection of data and going through them one by one. It could be doing counting in some other mechanism.

现在我把count用双引号标起来，不是说把它命名为一个字符串，而是说，这是一个通用的计数器,它可能是每一次减1的整数,也可能是拿一个集合的数据然后,一个一个的访问它们,也可能是以某种机制来计数。
