+=== About site search UI dependencies
+
+Additional tasks must be performed in order for the site search functionality on {url-site}[docs.datastax.com] to work properly.
+These tasks only need to be performed when changes are made to the following files:
+
+[%header.autowidth.stretch]
+|===
+|Files |Tasks
+
+|{url-project}/blob/main/gcx/algoliaSearch/index.html[_gcx/algoliaSearch/index.html_]
+|Copy this file to the _/en/search_ directory on the {url-coppi}/en/search/[coppi] and {url-docs-preview}/en/search/[docs-preview] servers.
+
+|{url-project}/tree/main/gcx/algoliaSearch/src[_gcx/algoliaSearch/src/*_]
+|Copy these files to the _playbooks/supplemental-ui_ directory in the {url-docs-home}/tree/main/playbooks/supplemental-ui[docs-home] repository.
+|===
+
+In the {url-docs-home}[docs-home] repository, the {url-docs-home}/blob/main/playbooks/site-local-home.yaml[_site-local-home.yaml_] and {url-docs-home}/blob/main/playbooks/site-publish-home.yaml[_site-publish-home.yaml_] playbooks are configured to incorporate the files from the _supplemental-ui_ directory into the assets directory of the generated site:

+  - path: css/siteSearch.css
+    contents: ./supplemental-ui/siteSearch.css
+  - path: js/siteSearch.js
+    contents: ./supplemental-ui/siteSearch.js
+  output_dir: assets
+----
+
+Whenever files are changed or added within the _supplemental-ui_ directory, the `home` docset must then be built and deployed to all of the docs servers to ensure that the servers have the latest site search assets.

 == Development quickstart
 
 This section offers a basic tutorial to teach you how to set up the UI project, preview it locally, and bundle it for use with Antora.
