Thanks, CandTFHA, for your post and for your example. It's a pretty good example of an admittedly poor user experience. FWIW, it came from the desire of being able to help people find the other people associated with a record (in this case the birth mother). Reason notwithstanding, it's not great. While I can't promise anything right now, I can say that we are looking at ways to improve this (some might say "fix this") specific situation.
I am in the process of evaluating how exact search does and should work and would welcome other specific examples (different in type than this one) of where exact search doesn't do as some might expect. Please be sure to include enough details for me to reproduce your query (including a URL, too).
