クエリーの形

{
        size: # number of results to return (defaults to 10)
        from: # offset into results (defaults to 0)
        fields: # list of document fields that should be returned - http://elasticsearch.org/guide/reference/api/search/fields.html
        sort: # define sort order - see http://elasticsearch.org/guide/reference/api/search/sort.html

        query: {
            # "query" object following the Query DSL: http://elasticsearch.org/guide/reference/query-dsl/
            # details below
        },

        facets: {
            # facets specifications
            # Facets provide summary information about a particular field or fields in the data
        }

        # special case for situations where you want to apply filter/query to results but *not* to facets
        filter: {
            # filter objects
            # a filter is a simple "filter" (query) on a specific field.
            # Simple means e.g. checking against a specific value or range of values
        }
}
