Cloud Firestore 查询是否仍然区分大小写? [英] Are Cloud Firestore queries still case sensitive?

问题描述

Firebase 实时数据库以区分大小写的方式接受带有字符串的查询.

Firebase Realtime Database accept queries with strings in case sensitive manner.

这仍然适用于 Firestore 吗?

Does this still apply for Firestore?

推荐答案

是的，查询仍然区分大小写.

Yes, queries are still case sensitive.

要支持不区分大小写或任何其他规范化，您需要编写一个单独的字段，其中包含规范化版本并对其进行查询.例如

To support case-insensitive or any other canonicalization you'll need to write a separate field that contains the canonicalized version and query against that. For example

db.collection("users").where("name", "==", "Dan")
db.collection("users").where("name_lowercase", "==", "dan")
