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

$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?
