Parameterized Queries having IN clause not working as expected in blazer tool of ruby-on-rails

Question

Here is the example of MySQL connector based Blazer Query

SELECT * FROM customers where email_domain in ({domains})

When I pass ?domains=ibm.com it works however if I pass ?domains=ibm.com,ibm.co.in Blazer modifies the query like this:

SELECT * FROM customers where email_domain in ('ibm.com,ibm.co.in')

How can I pass parameter or variable to form the query correct as MYSQL doesn't support explode function to generate an array as well.

You can make use of https://www.w3schools.com/sql/func_mysql_find_in_set.asp,

SELECT * FROM customers WHERE FIND_IN_SET(email_domain, {domains})
