Those two places accept regex from user requests which could lead to https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS

probably it should be a list of topics, or some simple language with asterisk for example, or anything else to remove this vulnerability, allowing to pass regex directly is not good
