It looks like the environment variable is being passed. However, the search bar only shows up in this page: https://dpf.docs.pyansys.com/version/stable/search.html

I am suspecting now about the Sphinx version.

docs build will only trigger if the PR is not draft, so changing the PR from draft to test

[Revathyvenugopal162]

i reverted the sphinx version back to 5.3.0 and the ci passes. we need to
investigate further to see the issue with the sphinx upgraded version.

[Revathyvenugopal162]

The build failed with Sphinx 7.2.6, prompting me to switch to version 7.1.0. The underlying issue with the search bar was that the 'pydata sphinx theme' was mistakenly included as an extension in the 'conf.py' file, causing it to override the desired 'ansys sphinx theme' and consequently affecting the search functionality. Now the search is working , please see the video attached took with artifacts.
