When searching using a Maypole application, or when creating a new item,
there is a need to be able to choose one among a number of
possibilities. For example, you might want to search only for beers made
at a particular brewery. The normal interface for doing this is very
good - a dropdown box listing all the possible choices and you select
one. This is an excellent user interface where the number of choices is
relatively small, such as choosing a brewery, but is not so good if
there are many possible answers, such as choosing one out of all the
pubs in the world.
I've finally managed to get something working to solve this. It's a
bunch of Perl, TT and Javascript that pops up a search window to let the
user identify the required item. It's still fairly raw, it's too
complicated, it means hacking the code in lots of places and it's just
not pretty but I've put a description here:

I'd welcome any feedback.
Cheers, Dave
