Querybase中的多个where子句不起作用

Question

Querybase中的多个where子句不起作用

这是我的代码

    <script src="https://unpkg.com/querybase@0.6.0"></script>
    <script>
     const databaseRef = firebase.database().ref().child('people');
     const querybaseRef = querybase.ref(databaseRef, ['name', 'age', 
     'location']);

      // Automatically handles composite keys
      querybaseRef.push({ 
        name: 'David',
        age: 27,
        location: 'SF'
      });

      // Find records by multiple fields
      // returns a Firebase Database ref
      const queriedDbRef = querybaseRef
       .where({
         name: 'David',
         age: 27
       });

      // Listen for realtime updates
      queriedDbRef.on('value', snap => console.log(snap));
     </script>

它给了我这些信息

  

如果尚未添加此规则，则可以大大提高实时数据库查询的性能：

"people": {
  ".indexOn": ["querybase~~YWdl", "querybase~~bG9jYXRpb24=", "querybase~~bmFtZQ=="]
}
