We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.

We use this method in two different scenarios. In an AJAX request, we
don't want to return every booth if the search is blank. However, in a
normal HTTP GET request, we want to return every record when the search
is empty, as we do everywhere else.
It's possible the behaviour of the AJAX call is unusual, since it
searches all booths, and not just the ones assigned to a poll. If we
changed this behaviour, we could simplify the code and remove the
`quick_search` method.
