How to combine two filters in search api views?

Question

I have a search index which is indexing both content and files.

I have configured the search api views which displays the search results.

On this view, I have a filter on type which displays the content types as links using better exposed filter.

Is there any way to add another option to the same filter files but clicking on it will display files in the search results only.

Is it possible? Any custom solution hint?

I have tried the combined global filter but that only works with fields not with rendered entity.

Answer 1

I used an aggregated field of search api. And combined the Content: content type and Media: bundle fields.

And used that field in the search api views filter.

But the filter was a text field. So to display it as links, I have created a custom views filter for that aggregated field.
