For well-distributed points, nearest neighbor search is often near O(logn)O(\log n)O(logn) in practice. In the worst case (all points clustered tightly or along a line), it can degrade to O(n)O(n)O(n), but this is uncommon with typical spatial data.
This will ask Ostrich for a string that does not match our regex, but does match type="email", meaning that the regex is in some sense more restrictive than the default browser validation of email addresses. These regexes would actually do something if attached to an input element with type email, since they would exclude any string that satisfies the constraints.
