DataTable server-side filtering: access the raw query string?

Say a user types something into the filter box that Dash can’t parse - say they just type Bolivia when what they want is probably eq Bolivia or whatever.

Is there a way for me to access the raw string that they typed in? That way I could build a DataTable where the user just types in raw strings to filter for words, without having to know any query syntax

Oh and to put this in context, I can currently achieve this by using the Input component, but it ends up in an awkward place because I don’t know any neat way to put it where the column filter goes
