Above is the code for my search Functionality, where I am using custom post type blog and custom taxonomy that is blog_taxonomy. I am able to get results only from tax_query or title.

I want them both searchable, as user either enters taxonomy name or post title in search bar. How to implement both ? tax_queries as well as commented 'title'.
