How to search for whether I have used any passwords starting with letter A and ending with letter B

Thank you for your answer! However, I'd rather not export all my passwords into plain text as that kind of defeats the object of storing them securely in the first place.
Should I take it from your answer that there's not a way to do this in 1Password?
And if so is there a way I can suggest this as a future enhancement? I think it would be useful for many people since this seems to be a standard alert that Experian produces.

Thank you again for taking the time to reply :-)
