[DSL] handle multiple values (array) about elasticsearch-dsl-ruby

[andreasklinger]

@defgenx thanks for getting back!

Ok got it!

The reason why this was confusing for me:

I would have expected

   must do
    bool do
      should do
        term color: red
        term color: blue
      end
    end
   end

to create

            "must": [
                {
                    "bool": {
                        "should": [
                            {"term": {"color": "red"}},
                            {"term": {"color": "blue"}}
                        ]
                    }
                }
            ]

But based on my experience so far (might be wrong) it just creates the first "term" and drops the second one silently without any error

            "must": [
                {
                    "bool": {
                        "should": [
                            {"term": {"color": "red"}},
                        ]
                    }
                }
            ]

No error message - just different json output than i'd have expected from the ruby dsl (assuming it's meant to mirror the json syntax)

must do
    bool do
      should { term color: red }
      should { term color: blue }
      end
    end
   end

creates the correct result as you described

I think this issue could be solved just by improving documentation

@andreasklinger It is by design.

Here is a link for complex queries. Maybe this can help you a little : https://github.com/elastic/elasticsearch-rails/blob/master/elasticsearch-rails/lib/rails/templates/searchable.dsl.rb#L73

You can use a terms query for your 'color' field and delete the nested bool query (not tested but I think it should work).
