javascript - 无效查询。您不能使用多个 'in' 过滤器

Question

this.ref.collection("users", ref => ref.where("uid1","in", [reciverId, senderId])
        .where("uid2","in", [reciverId, senderId]))

给我错误，例如

"Invalid query. You cannot use more than one 'in' filter"

Answer 1

更新:

自 2023 年 3 月 16 日发布 Firebase JS SDK 版本 9.18.0 以来，可以在查询中组合多个 in 子句。

但请注意，“Cloud Firestore 将查询限制为析取范式中的最多 30 个析取”，如 documentation 中所述。 (其中包括不同类型查询的析取数量示例)

旧答案:

这确实是 Firestore 的限制，如 documentation 中所述。 :

Limitations

Note the following limitations for in and array-contains-any:

• in and array-contains-any support up to 10 comparison values.
• You can use only one in or array-contains-any clause per query. You can't use both in and array-contains-any in the same query.
• You can combine array-contains with in but not with array-contains-any.
