Reason being that "hilbert"s aren't in v_basic_person. Reason
for this being that they don't have a NAMES row with
active=true. Reason for this being that we haven't yet solved
how to force unique-per-patient active=true rows in NAMES.

See above, problem with missing in v_basic_person due to
missing active=true in names.

Ah, *now* you are getting sensible.
You have "dismiss previous record":

- at start of search
- at end of search if nothing found

This can be collapsed into:

- at start of search

resulting in

- new patient if patient found
- no patient if nothing found

BUT NOT (as I thought you previously suggested):

- when *indicating likely desire to soon start search* (eg by
  clicking into the search field)

What you suggest now makes sense. Or perhaps you were
suggesting that all along and I wasn't getting it right.

Technically this is the same as:

- dismiss at end of search *regardless* of search result

This is still a change to the current design concept "always
have an active patient". If people really think that is worth
the increased trouble in coding they better speak up and/or
start coding.

Hopefully so. However, even though you have shown to some docs
your way of dismissing patient records there still are a bunch
of commercial programs in widespread use here in Germany that
do adhere to "always have an active patient". They even go so
far as to load the last patient from the previous run or the
first patient in the database upon startup. I can tell you that
that does NOT confuse a few thousand German doctors. There's
evidence either way. In face of that evidence *I* would prefer
the option that's safer to code (since simpler).

Changed code to likely match suggestion.

but I am OK with that. The part that needs prettying is the
pick list on multiple patients.

This is again due to the missing active=True in names hence no
v_basic_person rows.
