如何避免 Google Maps API v3 中的 OVER_QUERY_LIMIT 錯誤？

<code class="javascript">// Function to handle geocoding requests
function getAddress(search, next) {
  geo.geocode({ address: search }, function(results, status) {
    // If geocoding was successful
    if (status == google.maps.GeocoderStatus.OK) {
      // Process the result

      // Reset the delay
      delay = 0;
    }
    // If the error was OVER_QUERY_LIMIT
    else if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
      // Increase the delay and retry the request
      delay++;
      setTimeout(function() {
        getAddress(search, next);
      }, delay);
    } else {
      // Handle other errors
    }
    next();
  });
