2 is for minutes. Doctest confirms.
comment in catalogindex.py is buggy. Feel like adjusting? Perhaps
simply noting "per-minute"? Or perhaps it would be nice to make some
constants in interfaces.py around where the vocabulary is made?

I suggest hourly for date-based searches *if multiple time-zones are
in effect*, so one person's date would not be the same as someone
else's for an event that happens at a particular (UTC) time.
If you don't care about that use case, 0 should work.

comment error, as above.
