I am using search api views for site search.
I have 4 content types
A, B, C and D.
In the views filter when I expose a content type filter, it display as following on the search page
All A B C D
I want to combine the
C and D content types.
All A B Combined
Combined will be a custom text and when click , it should filter the content with Content type
C and D.
Is it possible with search api or is there any workaround?
