  ## Getting started
  Run `yarn start` in the root directory, and then navigate to [/search](http://localhost:3000/search)to check out the plugin.
  +
  +### Working on the search platform
  +
  +Currently, the search experience available in Backstage is 100% on the front-end, and only looks at the Software Catalog. We are actively developing [a more complete search platform](https://backstage.io/docs/features/search/search-overview), which will replace the current experience when ready.
  +
  +In order to work on the new search platform, you will need to be aware of the following:
  +
  +- **The use-search-platform feature flag**: The new search platform will move the primary search page to the App-level, out of the search plugin. You'll need to enable this feature flag to work on the net platform.
  +- **App SearchPage Component**: You'll find a new search page under `/packages/app/src/components/search`. When ready, we'll add an equivalent page to the `@backstage/create-app` template.
  +- **Backend**: Don't forget, a lot of functionality will be made available in backend plugins:
  + - `@backstage/plugin-search-indexer-backend`, which is responsible for the search index management
  + - `@backstage/plugin-search-backend`, which is responsible for query processing
  +
  +As you work, be sure not to break the existing, frontend-only search page.
