To show forks in repository search results, add fork:true or fork:only to your query. For more information, see Searching for repositories.

Repository search

The fork:true qualifier finds all results that match your search query, including forks. The fork:only qualifier finds only forks that match your search query.

Qualifier	Example
fork:true	github fork:true matches all repositories containing the word "github," including forks.
fork:only	github fork:only matches all fork repositories containing the word "github."
forks:>n fork:only	forks:>500 fork:only matches repositories with more than 500 forks, and only returns those that are forks.

Code search

GitHub code search uses is:fork instead of fork:true to include forked repositories in code search results. To exclude forks, use NOT is:fork. For more information, see Understanding GitHub Code Search syntax.

Qualifier	Example
is:fork	android language:java is:fork matches code with the word "android" that's written in Java, in forked repositories.
NOT is:fork	android language:java NOT is:fork matches code with the word "android" that's written in Java, excluding forked repositories.
