# The following checks are performed:
#
# - index_check: checks if the lunr.js index is built. There's two files when the
#   index is built: 'lunr-index.json' and 'lunr-map.json'.
# - dev_check: when ALGOLIA_SEARCH is set to 'false' the div we're looking for
#   is set to 'js-lunr-form'. Otherwise, it's set to 'docsearch' by default.
#   This is defined in
#   https://gitlab.com/gitlab-org/gitlab-docs/-/blob/83ebc0de813c6e916b522a9203a6182d7425dd20/content/index.erb#L20-24.
