Candidate Search | Boolean expression to search for a candidate born within a date range

Hi team,

our client asks for the opportunity to search for a candidate by using a "filter" related to the date of birth.
In order to workaround this, we are thinking about the possibility to enter in the search bar of Candidate Search a Boolean expression to be able to search candidates born between "start date" and "end date".

Have you any suggestion o experience about something like this?
Could you please let me know if this workaround can work and what type of boolean expression we can enter?

Thanks in advance

Tommaso
