+### Adding custom behaviors to ResultMapper - CustomResultMapper
+
+Define new class implementing ResultMapper
+
+```java
+public class CustomResultMapper implements ResultsMapper{
+
+    private EntityMapper entityMapper;
+
+    public CustomResultMapper(EntityMapper entityMapper) {
+        this.entityMapper = entityMapper;
+    }
+
+    @Override
+    public EntityMapper getEntityMapper() {
+        return entityMapper;
+    }
+
+    @Override
+    public <T> T mapResult(GetResponse response, Class<T> clazz) {
+        return null;  //Your implementation
+    }
+
+    @Override
+    public <T> FacetedPage<T> mapResults(SearchResponse response, Class<T> clazz, Pageable pageable) {
+        return null;  //Your implementation
+    }
+}
+
+```
+
+Inject your custom implementation to template
+
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<beans xmlns="http://www.springframework.org/schema/beans"
