sql - Couchbase N1QL-内联正则表达式捕获组替换？

Question

UPDATE SOME_BUCKET as doc USE KEYS ["USER_ACCESS::123456::SOME_ROLE", "MORE KEYS HERE...", etc]
loc.id = REGEXP_REPLACE(loc.id, "(.*) - (.*)", "$1-$2") FOR loc IN locations END
RETURNING doc

在这里设置“loc.id”只是为其分配字符串文字替换值，“$ 1- $ 2” ，而不是对捕获组的反向引用。
Couchbase Server运行GoLang regex语法，这显然可能不支持反向引用？有什么选择吗？
