Thanks to all for your comments!
About the DSL, my goal was not reinvent the wheel, but just provide a
simple way to access Elasticsearch.
I wanted to be closer to the Java API that provides classes such as
GetRequest, CountRequest, SearchRequest, DeleteRequest, ...
So, I have just reused these concepts.
The query you can provide for some commands (search, for example) is
exactly what you can provide to Elasticsearch, nothing more, nothing less.
The main problem is how to handle the json documents returned by
Elasticsearch.
I have decided to flatten the json document.
If you have:
```json
{
"field1": "value1",
"field2": {
"field3":"value3",
"field4":[1,3]
}
}
```
You will get a something like this:
field1 | field2.field3 | field2.field4[0] | field2.field4[1]
------- | -------------- | ------------------ | -----------------
value1 | value3 | 1 |2
I will fix the code in this way, are you ok ?
