// We have indices on id, name, total credit, and RAC.
// So we provide the following searches:
// - new users in last N days (1, 7)
// - users with names starting with X
// - users ordered by decreasing total credit
// - users ordered by decreasing RAC
//
// In addition you can filter by:
// - a given country
// - with/without profile
// - with/without team
//
// We don't do the filtering in the SQL, because that would
// lead to table scans in the worst case.
// Instead we use the following policies:
// - a given search can scan no more than MAX_ROWS rows
// - a given search can return no more than MAX_RESULTS results
//
// here's how we do this:
// result_list = empty
// while n<MAX_ROWS
// enumerate rows w/o filtering, limit n, 1000
// (read only the fields we need for display)
// scan through batch, doing filtering, appending to result_list
