Searching for multiple hits in multiple cities

Our company is currently working with react-instantsearch to allow our users to search for several of our properties based on city, max price etc.
One of our next evolution would be to allow our users to search for properties in different cities but I am currently struggling to pass multiple parameters (cities in our case) in the query.
I don’t know if it’s possible and I tried to search for similar cases but didn’t find anything conclusive.
