+# Missing Filter
+
+> More info about missing filter is in the [official elasticsearch docs][1]
+
+Returns documents that have only null values or no value in the original field.
+
+## Simple example
+
+```JSON
+{
+ "filter" : {
+ "missing" : { "field" : "user" }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$missingFilter = new MissingFilter('user');
+
+$search = new Search();
+$search->addFilter($missingFilter);
+
+$queryArray = $search->toArray();
+```
