Yeah... These are kind of complicated, but very flexible. They're also getting better docs soon-ish.
max are the range of the sorted results to return.
So, if you order a list of questions (pick your API method of choice) by
votes, you can set
min to 5 and
max to 10 to only return questions that have a score of at least 5 and no more than 10.
If you were to sort by
creation, you could instead only return questions created between (inclusive) the 1st and 15th of June 2009 by setting
min to 1243832400 and
max to 1245042000.
Comparing pure strings (as in
name) gives you a lexographic range though the exact one is something of an implementation detail.
max causes that end of the range to by unbound. So you could use get all questions with at least a score of 10 by setting
min to 10,
votes, and omitting
max on the appropriate methods.
