Body

GitHub Code Search Limitations says the following...

The current limitations on indexed code are:

• Vendored and generated code is excluded
• Empty files and files over 350 KiB are excluded
• Lines over 1,024 characters long are truncated
• Only UTF-8 encoded files are included
• Very large repositories may not be indexed

Can you elaborate on what would be considered a very large repository? Is there a max size of a .git directory, or a max number of files in the repository, or some other limit?

[look]

The exact limits are subject to change which is why we haven't documented them, but it looks at both the size of the Git repository and the number of paths. The size limit is around 50 GB and the path limit varies by repo but is at least 75,000.
