Thanks for the question.
1. Please run through these Standard Troubleshooting Steps, since it looks like you have some 3rd parting integrations.
2. Please provide steps to replicate on the stock theme with expected/unexpected behavior so that I can help - Read Me: File a Support Request
Warning issue resolved, another question I want to ask that currently this search works only for wordpress post content while I want to search within pages text of wordpress also.
Please suggest any method.
Thanks for the question. The extended functionality that you are looking for is not native to WordPress, and the theme does not extend this functionality, nor does it advertise it - so this falls beyond the scope of theme support.
