Fixed a trailing whitespace.
Applied pre-filter to _view/type-year for #docs<=500.
Switched mode when building the autocomplete source.

If the application has to deal with 100 or more unique keys, it could as well
use the ungrouped results that are responded way faster.
With that many keys, it seems unlikely that the client has to process an
identical key more than 10 times anyway.
Added some explanation.
Removed offset coordinates in upload.html.

This has been a glitch since v1.0.9 I am afraid.
TODO: Re-route docs with obviously matching doc.time or something.
