+  Named properties in the expression object will only match against properties on the **same level**.
+  Previously, named string properties would match against properties on the same level **or deeper**.
+
+    Before:
+
+    ```js
+    arr = filterFilter([{level1: {level2: 'test'}}], {level1: 'test'});   // arr.length -> 1
+    ```
+
+    After:
+
+    ```js
+    arr = filterFilter([{level1: {level2: 'test'}}], {level1: 'test'});   // arr.length -> 0
+    ```
+
+    In order to match deeper nested properties, you have to either match the depth level of the
+    property or use the special `$` key (which still matches properties on the same level
+    **or deeper**). E.g.:
+
+    ```js
+    // Both examples below have `arr.length === 1`
+    arr = filterFilter([{level1: {level2: 'test'}}], {level1: {level2: 'test'}});
+    arr = filterFilter([{level1: {level2: 'test'}}], {$: 'test'});
+    ```
