+When rendering websites locally, `site.github.url` doesn't get resolved
+properly unless GitHub PAT are set up and available in the environment.
+This leads to warnings and errors when trying to serve the site locally.
+To work around this, we use the `jekyll.environment` variable which is set to
+`development` when rendering the site locally, and set to `production` on
+GitHub where `site.github.url` will be defined.
+{% endcomment %}
+
+{% if jekyll.environment == "development" %}
+{% assign search_domain_url = "" %}
+{% elsif jekyll.environment == "production" %}
+{% assign search_domain_url = site.github.url %}
+{% endif %}
