GitHub Announces Preview of its Improved Code Search Dump


GitHub recently announced to have rolled out a new technology preview for substantial improvements to searching code on GitHub.

“We want to give you an early look at our efforts and get your feedback as we iterate on helping you explore and discover code—all while saving you time and keeping you focused,” writes Pavel Avgustinov, product engineer at GitHub.

Once the technology preview is enabled for an account, the developer can try it out at Initially, GitHub has created a separate interface for the new code search and the team being happy with the feedback, is ready for wider adoption and integrate to main experience.

  • Scope your searches with org: or repo: qualifiers, with auto-completion suggestions in the search box.
  • Refine your results using filters like language:path:extension:, and Boolean operators (ORNOT). Search for definitions of a symbol with symbol:.
  • Get your bearings quickly with additional features, like a directory tree view, symbol information for the active scope, jump-to-definition, select-to-search, and more
