I have a collection with documents that follow the following model:

How can I get all the documents of that collection where at least one object inside the "services" array contains a doctorId property with the value of 1, the firebase library in react.
I tried using the method:

But it doesn't work, because apart from the doctorId property, the object inside the "services" array has other properties, so it doesn't match

**得分**: 0
`array-contains` 和 `array-contains-any` 运算符将指定的值与数组中的每个**整个**项进行比较，如果存在精确、完全匹配，则返回文档。无法用于部分匹配。
通常的解决方案，与NoSQL数据库一样，是添加额外的数据以支持用例。例如，在这里，您可以添加另一个顶层数组字段，其中包含所有医生的ID：

然后，您可以使用 `array-contains` 对该字段进行查询：

The `array-contains` and `array-contains-any` operators compare the value you specify against each **entire** item in the array, and returns the document if there is an exact, complete match. You can&#39;t use them for partial matches.
The common solution is, as usual with NoSQL databases, to add additional data to allow the use-case. Here for example, you can add another top-level array field with all the doctor IDs:

And then you can query on that field with `array-contains`:
