How to make a regular expression to get the part of a string after a certain word?

https://mydomen.ru/category/search?area=32&city=31...

You need to separate the line after https://mydomen.ru/category/search

area city and so on can be different

Regular something like this: /\?(.*)/

Then you can split the string into pairs by sign &and then split each pair into key and value by sign =.
But it's much better to use the built-in URL interface in JS :

const url = new URL('https://mydomen.ru/category/search?area=32&city=31');
console.log('host', url.host);
console.log('search', url.search);
const city = url.searchParams.get('city');
console.log('city', city);
