如何在github上搜索以获得完全匹配（就像Google的报价一样）

How to search on github to get exact matches (like what quotes do for Google)

我可以使用像"system <<-"这样的引号从谷歌中搜索完全匹配的内容。如何为Github做类似的事情？我做不到。

不能。Github官方搜索规则：

Due to the complexity of searching code, there are a few restrictions
on how searches are performed:

Only the default branch is considered. In most cases, this will be the master branch.

Only files smaller than 384 KB are searchable.

You must always include at least one search term when searching source code. For example, searching for language:go is not valid, while amazing language:go is.

At most, search results can show two fragments from the same file, but there may be more results within the file.

You can't use the following wildcard characters as part of your search query:
. , : ; / \ ` '" = * ! ? # $ & + ^ | ~ < > ( ) { } [ ]
The search will simply ignore these symbols.

解决办法：

如果需要在单个存储库中搜索，可以在本地克隆它，并使用grep精确查找字符串：

1	grep -r"system <<-" /repository_dir

今天我在Github上的任何一个repo文件中，都试图寻找一个与filter class完全匹配的文件logback.xml。我提出了下面的问题，完成了这项工作。

1	"filter class" in:file filename:logback.xml

要使用引号进行精确匹配，您需要使用"in:file"修饰符进行搜索。匹配不太精确，"class"这个词必须跟在"filter"后面，但两个词之间似乎可以有0个或更多的空格或符号字符。
