Fuzzy Like This Field Queryedit

Warning

Deprecated in 1.6.0.

This query will be removed in Elasticsearch 2.0.

The fuzzy_like_this_field query is the same as the fuzzy_like_this query, except that it runs against a single field. It provides nicer query DSL over the generic fuzzy_like_this query, and support typed fields query (automatically wraps typed fields with type filter to match only on the specific type).

{
    "fuzzy_like_this_field" : {
        "name.first" : {
            "like_text" : "text like this one",
            "max_query_terms" : 12
        }
    }
}

fuzzy_like_this_field can be shortened to flt_field.
