We found a peculiar problem in our users when they enter their data. They tend to enter similar entries sometimes.
I'll cite an example here.
If there is a customer with the name ABC Electric Corporation already in the system, they sometimes enter the ABC Electric Corp. or sometimes ABC Elec. Corporation
We use this node package to show a set of similar names to the user when he is creating a new customer.
The question is when should we really prompt the user that he may be entering a duplicate customer?
We show the set of similar names when more than x% matches? What should be value of x?
