name: Sync search indexes

# **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.
