[Search] Search query is missing entities in specific edge case

[KDederichs]

Describe the bug
I've run into a specific search edge case where it won't search on nested entities when you search on an entity in 2 different parent entities.

To Reproduce

Have an Entity Foo with something you want to search on, lets call it fooBarBaz.

Then define 2 new entities Bar and Baz that both reference Foo $foo using ManyToOne relations.

Lastly have an entity that contains a ManyToOne reference to both Bar $bar and Baz $baz let's call that BarBaz

Then you configure the search in your your BarBazCrudController like this:

    public function configureCrud(Crud $crud): Crud
    {
        return $crud
            ->setSearchFields(
                [
                    'bar.foo.fooBarBaz',
                    'baz.foo.fooBarBaz'
                ]
             );
    }

In this case you'll only ever get the Bar entities that contain a matching Foo entity, the Baz ones will be omitted.

Looking at the query in the profiler I think it's related to how those are joined.
Which ever entity first joins the Foo entity will get searched, the rest will be skipped.
