 `has_reference`::
   (Optional, object) Filters to objects that have a relationship with the type and ID combination.
 
+`filter`::
+  (Optional, string) The filter is a KQL string with the caveat that if you filter with an attribute from your type saved object.
+  It should look like that savedObjectType.attributes.title: "myTitle". However, If you used a direct attribute of a saved object like `updatedAt`,
+  you will have to define your filter like that savedObjectType.updatedAt > 2018-12-22.
+
 NOTE: As objects change in {kib}, the results on each page of the response also
 change. Use the find API for traditional paginated results, but avoid using it to export large amounts of data.
