Defined in:
lib/jekyll/client_search/search_tag.rb

Overview

Liquid tag that renders the search form, status/results containers, and all runtime scripts in one line — config-driven so changing engines in _config.yml requires zero template changes.

{% search_form %}
{% search_form scripts_only %}  — just scripts (custom form HTML)
{% search_form no_scripts %}    — just form HTML (user loads scripts)

When client_search is disabled the tag renders nothing.
