如何在 GitHub 上搜索以获取精确的字符串匹配，包括特殊字符 [英] How to search on GitHub to get exact string matches, including special characters
问题描述
我可以使用像 "system <<-" 这样的引号从 Google 搜索完全匹配.
I can search exact matches from Google by using quotes like "system <<-".
如何为 GitHub 做同样的事情?
How can I do the same thing for GitHub?
推荐答案
你不能.GitHub官方搜索规则:
You can't. The official GitHub searching rules:
由于搜索代码的复杂性，有一些限制关于如何执行搜索:
Due to the complexity of searching code, there are a few restrictions on how searches are performed:
- 仅考虑默认分支.在大多数情况下，这将是 master 分支.
- 只能搜索小于 384 KB 的文件.
- 只能搜索少于 500,000 个文件的存储库.
- 在搜索源代码时，您必须始终包含至少一个搜索词.例如，搜索
language:go是无效的，而amazing language:go是. - 搜索结果最多可以显示来自同一文件的两个片段，但文件中可能会有更多的结果.
- 您不能在搜索查询中使用以下通配符:
<代码>., : ;/` ' "= *！?# $ &+ ^ |~ <>( ) { } [ ]
搜索将简单地忽略这些符号.
- Only the default branch is considered. In most cases, this will be the master branch.
- Only files smaller than 384 KB are searchable.
- Only repositories with fewer than 500,000 files are searchable.
- You must always include at least one search term when searching source code. For example, searching for
language:gois not valid, whileamazing language:gois. - 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.
克隆并使用git-grep:
git 支持使用 git-grep 在源中搜索命令.只需克隆一个存储库并使用文件夹中的命令:
Clone and use git-grep:
git support searching in sources with git-grep command. Just clone a repository and use the command in the folder:
git grep "text-to-search"
替代方案:
我建议您尝试 ripgrep 工具，它既快速又简单.像 git-grep 一样工作，但看起来更好:
I recommend you to try ripgrep tool, it's fast and simple. Works like git-grep but looks nicer:
rg "text-to-search"
并且您可以使用标准的 grep 来搜索文件中的任何文本:
And you can use the standard grep to search any text in files:
grep -r "text-to-search" /repository
