FYI I remembered when debugging this that when you want to see what your
filter parameters are, a line like this
function(doc, req) {
throw JSON.stringify(req);
}
will make them show up in the Xcode logs. In the case of the first code I
tested, anything but numbers and true or "false" would fail to parse as a
parameter. Now it works great, but you may have to decodeURIComponent and
JSON.parse parameters in your filter function (or switch to a comma
separated list or something easier to decode.)
