Need help on running the multiple search index in single aggregate pipeline

I have created three different index on different collection in a database on MongoDB server side. Below are the one’s

With aggregation pipeline builder I am able to run only one search index.

How can I combine and run multiple search indexes of different collection in a same database and come up with single result set?

Hi @Basavaraj_Km and welcome in the MongoDB Community :muscle: !

$search must be the first stage in your pipeline and can’t be used in a $facet pipeline stage so I think this isn’t possible at the moment.

But maybe it’s possible to change the definition of your index so it does what you want with just one index? @Karen_Huaulme is this possible?
