It is mentioned in the breaking changes section of [elasticsearch 5.0.0](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_search_changes.html) that `query` is obsolete after filters and queries have been merged. What does that mean? Can someone explain this with an example?

You used to be able to write:

```auto
{
    "constantScore" : {
        "filter" : {
            "query" : {
                "query_string" : {
                    "query" : "this AND that OR thus"
                }
            }
        }
    }
}

```

This is saying that the filter named `query` is now gone. It isn't very clear though.

Thanks, that's more clear. Is the first query below still valid? I prefer to use the bool query.

# query

```
{
  "query":{
    "term":{
      "city":"Paris"
    }
  }
}

```

# bool query

```
{
  "query":{
    "bool":{
      "must":{
        "term":{
          "city":"Paris"
        }
      }
    }
  }
}
```

They are both fine, sure.
