| 1 | //! The search service: one search across all of g1t, and Explore. |
| 2 | //! |
| 3 | //! It covers everything public, and private content the viewer is a member |
| 4 | //! of: repositories (name, description, topics, README), code on default |
| 5 | //! branches, issues and pull requests, people and workspaces. Who may see |
| 6 | //! what is decided when the query runs, against the viewer's current |
| 7 | //! memberships and each repository's current visibility, never only when |
| 8 | //! something was indexed. |
| 9 | //! |
| 10 | //! Each `*Args` struct is the argument of the method of the same name, |
| 11 | //! served at `POST /rpc/<method>`. Mirrors `packages/contracts/src/search.ts`. |
