`todate` and `fromdate` always refer to creation date.

`min` and `max` are with respect to the current `sort`.  So, where `sort=votes` they place upper and lower bounds on the `score` of returned answers/questions.

They **can** overlap, but do not always do so.

Documentation has been updated to reflect that `min` and `max` can be of any number of types.

[`/search`][1] for example.
