Difficult to create arrays of items on an index

[blueo]

Currently it is quite difficult to index an array that is created by a custom function.
You can use the dot notation to index a relation eg Tags.ID and this will result in an array of IDs however you don't seem to be able return an array from a custom property and have it indexed eg

in search config

    App\MyObject:
          fields:
            some_field:
              property: getMyArrayOfThings

public function getMyArrayOfThings(): array
{
   return // do something that returns an array
}

this would be really useful for creating custom indexes and I think quite intuitive - eg returning an array should create an array on the index. Maybe I'm missing something here so open to correction on how this works.

I've implemented a change which allows this (at least with Elastic) in #97
