Flt Field Query
===============

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).


.. code-block:: js


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


Note
    **fuzzy_like_this_field** can be shortened to **flt_field**.


The **fuzzy_like_this_field** top level parameters include:
