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

Question

I can search exact matches from google by using quotes like "system <<-". How to do the similar thing for github? I can't make it work.

You can't. The official GitHub searching rules:

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.
• 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: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.

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"

Alternatives:

I recommend you to try ripgrep tool, it's fast and simple. Works like git-grep but looks nicer:

rg "text-to-search"

And you can use the standard grep to search any text in files:

grep -r "text-to-search" /repository
