+# Fuzzy Like This Field Query
+
+> More info about fuzzy like this field query is in the [official elasticsearch docs][1]
+
+The fuzzy like this field query is the same as the [fuzzy like this query][2], 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).
+
+## Simple example
+
+```JSON
+{
+    "fuzzy_like_this_field" : {
+        "name.first" : {
+            "like_text" : "text like this one",
+            "max_query_terms" : 12
+        }
+    }
+}
+```
+
+In DSL:
+
+```php
+$fuzzyLikeThisFieldQuery = new FuzzyLikeThisFieldQuery(
+    'name.first',
+    'text like this one',
+    [ 'max_query_terms' => 12 ]
+);
+
+$search = new Search();
+$search->addQuery($fuzzyLikeThisFieldQuery);
+
+$queryArray = $search->toArray();
+```
