Hi. Thanks for the effort.

This feature is not going to be so straightforward.

This change does show Washington as the first result when typing "wa" into the checkout, but it will not show any states that don't start with "wa" (e.g. Delaware, Iowa):

Also, this means that you cannot now find Washington with the search "ton", "ashington", etc.

What it needs is to show Washington as the first result when searching for "wa" and all of the other results need to be present in the same order they were before:

It's a much trickier issue, and I don't think we can solve it until we define what the correct algorithm should be.
