the tests fail locally, let me know if i can help

[lookacat]

from testing it on web i can say it works perfect, just cant approve the PR because i think someone from the ocis team has more knowledge of the topic

We are type asserting ln and rn multiple times here. Can't we solve that with a typeswitch? Like

right, ok := rn.(*bleveQuery.DisjunctionQuery)
switch left := ln.(type) {
default:
    if ok {
        left := bleveQuery.NewDisjunctionQuery([]bleveQuery.Query{ln})
        left.AddQuery(right.Disjuncts...)
        return left
    }
    fallthrough
case *bleveQuery.ConjunctionQuery:
    return bleveQuery.NewDisjunctionQuery([]bleveQuery.Query{ln, rn})
case *bleveQuery.DisjunctionQuery:
    if ok {
        left.AddQuery(right.Disjunkts)
    } else {
        left.AddQuery(rn)
   }
   return left	
}

Or similar. But we want to make the type assertions only once

The fallthrough doesn't work in this way.
I can rewrite but It became badly readable, sounds to me

		right, ok := rn.(*bleveQuery.DisjunctionQuery)
		switch left := ln.(type) {
		case *bleveQuery.DisjunctionQuery:
			if ok {
				left.AddQuery(right.Disjuncts...)
			} else {
				left.AddQuery(rn)
			}
			return left
		case *bleveQuery.ConjunctionQuery:
			return bleveQuery.NewDisjunctionQuery([]bleveQuery.Query{ln, rn})
		default:
			if ok {
				left := bleveQuery.NewDisjunctionQuery([]bleveQuery.Query{ln})
				left.AddQuery(right.Disjuncts...)
				return left
			} else {
				return bleveQuery.NewDisjunctionQuery([]bleveQuery.Query{ln, rn})
			}
		}

Imo better readable than the double type assertion. If you ask me I'd go with second solution. But up to you in the end...

[kobergj]

You could skip the last else though 😉
