+
+> **Примечание**: `location` и `search` являются регулярными выражениями в следующем формате: Символ процента ("%") соответствует любой последовательности из нуля или более символов в строке. Подчеркивание ("_") соответствует любому одиночному символу в строке. Любой другой символ соответствует самому себе или его эквиваленту в нижнем/верхнем регистре (сопоставление без учета регистра)

+    }
+}
+``````
+
+> **Примечание**: `account_tx_with_additional_info` имеет тот же формат, что и в запросе getbarteronaccounts
+
+> **Примечание**: Если `includeSmth` не указан в запросе, то `smth` вообще не будет в ответе json.
+
+> **Примечание**: `score_tx`, `comment_tx`, `comment_score_tx` и `account_tx_with_additional_info` - это просто необработанные транзакции, и связи между ними и предложениями должны быть построены на стороне клиента.
