我有以下文件的 firestore 集合：

[
  {
    start:       { geohash: 'u3qchtmpuy2d' },
    destination: { geohash: 'u3qcjvxfh9cs' },
    timestamp:   '28 June 2019 at 20:24:00 UTC+2',
    ...
  }
]

我试着像这样查询它（它的 Firestore Web SDK）

// 5-characters geohash is 4.89km × 4.89km
const start = 'u3qch';
const destination = 'u3qcj';
const timestamps = {
  min: firestore.Timestamp.fromDate(
    moment(someDateTime).subtract(10, 'minutes').toDate()
  ),
  max: firestore.Timestamp.fromDate(
    moment(someDateTime).add(10, 'minutes').toDate(),
  ),
};

firestore
  .collection('deliveries')
  .where('start.geohash', '>=', start)
  .where('start.geohash', '<', geohashEnd(start))
  .where('destination.geohash', '>=', destination)
  .where('destination.geohash', '<', geohashEnd(destination))
  .where('timestamp', '>=', timestamps.min)
  .where('timestamp', '<', timestamps.max)
  .get() …
