 name: Sync search indexes
 
-# **What it does**: This updates our search indexes after each deployment.
+# **What it does**: This workflow syncs the Lunr search indexes.
+#   The search indexes are checked into the lib/search/indexes directory.
+#   Search indexes are checked directly into the `main` branch on both the
+#   internal and open-source docs repositories. This workflow should be the
+#   only mechanism that the search indexes are modified. Because of that,
+#   repo-sync will not sync the search indexes because it should not detect
+#   a change.
 # **Why we have it**: We want our search indexes kept up to date.
 # **Who does it impact**: Anyone using search on docs.
 
+# **Testing: To test this workflow, use the workflow_dispatch event and trigger
+#   the workflow from the action tab. Select the branch with the changes to the
+#   workflow. Set `fetch-depth: 0` as an input to the checkout action to get all
+#   branches, including your test branch. Otherwise, you'll only get the main
+#   branch. For git lfs push and git push commands use the --dry-run switch to
+#   prevent pushes (e.g., git push --dry-run origin main --no-verify and
+#   git lfs push --dry-run public-docs-repo).
+#   The dry-run switch does everything but actually send the updates.

This process generates structured data for all pages on the site, compares that data to what's currently on search, then adds, updates, or removes indices based on the diff of the local and remote data, being careful not to create duplicate records and avoiding any unnecessary (and costly) indexing operations.
 
 The Actions workflow progress can be viewed (by GitHub employees) in the [Actions tab](https://github.com/github/docs/actions?query=workflow%3Asearch) of the repo.
 
-Because the workflow runs after a branch is merged to `main`, there is a slight delay for search data updates to appear on the site.
+## Manually triggering the search index update workflow
 
-## Manual sync from a checkout
+You can manually run the workflow to generate the indexes after you push your changes to `main` to speed up the indexing when needed. To run it manually, click "Run workflow" button in the [Actions tab](https://github.com/github/docs-internal/actions/workflows/sync-search-indices.yml).
 
-It is also possible to manually sync the indices from your local checkout of the repo, before your branch is merged to `main`.
+## Generating search indexes for your local checkout
 
-**Prerequisite:** Make sure the environment variables `ALGOLIA_APPLICATION_ID` and `ALGOLIA_API_KEY` are set in your `.env` file. You can find these values on [Algolia](https://www.algolia.com/apps/ZI5KPY1HBE/api-keys/all). _Remove this paragraph when we switch to Lunr._
+You can locally generate search indexes, but please do not check them into your local branch because they can get out-of-sync with the `main` branch quickly.
+
+To locally generate the English version of the Dotcom search index locally, run `LANGUAGE=en VERSION=free-pro-team@latest npm run sync-search`. See [Build and sync](#build-and-sync) below for more details. To revert those files run `git checkout lib/search/indexes`.
