Extending Project Search — Builder 50.0 documentation

# Extending Project Search

Builder provides a global search box in the top right of the workbench. It can be extended to provide new types of search results.

For example, the `file-search` extension provides search results based on files found in the project tree.

Additionally, the `code-index` extension provides search results based on an index built from your project code.

To add new search results, implement the `Ide.SearchProvider` interface in your plugin.
