inq filter with case insensitive

[engrwaqasali]

whereBuilder.inq('country', ["Pakistan", "india"]);
how do i make this work for case insensitive so that i can get pakistan and Pakistan and INDIA and inDia you get the idea
something we do for like filter where we use ilike for case insensitive

currently I did it with regexp

const regex = new RegExp(countries.join('|'), 'i');    
whereBuilder.regexp('country', regex);

this seems more powerfull

cause it can match for United States, India

with input
["united", "India"]
["United STATEs", "ndia"]
["united sta", "ind"]
["states", "INDIA"]
["STates", "DIA"]
