* Core modification When hyper scan failed, we should not set_error in FunctionContext. Since set_error will try cancel query, but actually we want to fall back to re2 in this case. * Some refactor Rename FunctionRegexp so that we can distinguish regexp match with regexp_extract. * Reproduce ```cpp SELECT * FROM regexp_test_chinese WHERE city REGEXP "^上海｜^北京" ORDER BY id; ``` Note, the `|` in above sql is a Chinese character.
