I am working on Search API view. There is a Date Exposed filter. The requirement is we have to filter based on Month-Year instead of Day-Month-Year. But there is no Granularity option to select for Search API View.
For simple views, there is Granularity option to select Day/Month or year. See in attached screenshot 
.
I am able to achieve this functionality in simple view see in the screenshot
Can someone help me to achieve this functionality for Search API views?
