+Multi type search
+===============
+
+If you want to limit your search to just few selected types in given index you could do that this way:
+
+```yaml
+fos_elastica:
+    indexes:
+        app:
+            types:
+                article:
+                    mappings:
+                        title: ~
+                        desc: ~
+                    # ....
+                news:
+                    mappings:
+                        title: ~
+                        desc: ~
+                    # ....
+```
+
+```php
+$query = 'search-string';
+$mngr = $this->get('fos_elastica.index_manager');
+
+$search = $mngr->getIndex('app')->createSearch();
+$search->addType('article');
+$search->addType('news');
+$resultSet = $search->search($query);
+
+$transformer = $this->get('fos_elastica.elastica_to_model_transformer.collection.app');
+$results = $transformer->transform($resultSet->getResults());
+```
