It is inline with elasticsearch's usage of nested documents

The nested type is a specialized version of the object data type that allows arrays of objects to be indexed

see elasticsearch nested docs

In the case of foo.bar.baz

1. if bar is an array of objects, we return foo.bar.
2. if bar is not an array, it does not qualify to be a nested property (according to elasticsearch) and we return null.

This allows Filter and Match queries such as

GET /object-array-object-string/_search

{
  "query": {
    "nested": {
      "path": "object.array",
      "query": {
        "bool": {
          "must": [
            { "match": { "object.array.object.property": "search-value" } }
          ]
        }
      }
    }
  }
}

can you fix phpunit tests on elasticsearch? to run them:

cd src/Elasticsearch
composer update
./vendor/bin/simple-phpunit

Yep. currently rethinking the approach.

The resulting nested match query seems to be a bit different from what elasticsearch has documented

It still works, im not sure if it is a hidden feature or a bug. So will confirm with them and proceed accordingly.
