how to query for values in an object with elasticsearch

i am trying to figure out how to query on specific fields in an object with elasticsearch. my indexed document looks like this:

{
    name : 'thename'
    meta : {
        title : {value: 'foo is the title'}
        headline: {value : 'bar is the headline'}
    }
}

how would i for example create a query against meta.title.value?
is this actually supported?
i can can query for those values without specifying a key like:

{
    query: 'foo'
}

and i get the correct results back but i cant figure out how to do it if i just want to search for that specific key inside the meta object.
more specifically i am using mongoose with mongoosastic if that makes any difference.

here my document mapping on elasticsearch:

"mappings": {
    "asset": {
        "properties": {
            "kind": {
                "type": "string"
            },
            "meta": {
                "properties": {
                    "description": {
                        "properties": {
                            "value": {
                                "type": "string"
                            }
                        }
                    },
                    "headline": {
                        "properties": {
                            "value": {
                                "type": "string"
                            }
                        }
                    },
                    "visible": {
                        "type": "boolean"
                    }
                }
            }
        }
    }
}

Solution

Example of query by a specific field:

{
    "query": {
        "match" : {
            "name" : "thename"
        }
    }    
}

In the example above, "name" is the name of the field you want to query for.

For the case of the nested data (meta.title, for example), you can take a look in the section "How to query nested fields" I posted in this topic https://stackoverflow.com/a/25203970/3917476 or check the "nested query" and "nested type" documentation: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html#query-dsl-nested-query.

However, I find you should read the ElasticSearch documentation, because querying by a specific field is one of the most basic things (IMHO). http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-queries.html

There are many types of queries you can create. Try to go through most of them (for start, I suggest you "match", "term", "bool", "nested", "fuzzy" and "wildcard") creating small examples.

Edit 1

I have a suggestion for you: do not create fields with the name "value", otherwise we will have to create useless nested queries.

This is a suggestion for your mapping:

"mappings": {
    "asset": {
        "properties": {
            "kind": {
                "type": "string"
            },
            "meta": {
                "properties": {
                    "description": {
                        "type": "string"
                    },
                    "headline": {
                        "type": "string"
                    },
                    "visible": {
                        "type": "boolean"
                    }
                }
            }
        }
    }
}

With this mapping, you use the following query:

{
    "query": {
        "nested": {
            "path": "meta",
            "query": {
                "term": {
                    "description": "foo"
                }
            }
        }
    }
}

Otherwise you may use this query to your existing mapping:

{
    "query": {
        "nested": {
            "path": "meta",
            "query": {
                "nested": {
                    "path": "description",
                    "query": {
                        "term": {
                            "value": "foo"
                        }
                    }
                }
            }
        }
    }
}
