能不能帮忙看一下，为什么大量查询超时？

粘贴的图像615x501 148 KB

索引已经做了，但是不知道是否设置有问题，没有生效。

userQuery.equalTo("status", 1);
userQuery.equalTo("gender", !currentUser.get("gender"));
userQuery.notContainedIn("objectId", friendsIds);
userQuery.notEqualTo("extendUserTags", "rejectPaperPlane");
userQuery.lessThan("paperPlaneProperty_odd", 5);
userQuery.greaterThan("lastActTime", new Date(now.setMinutes(now.getMinutes() - 10)));

和

userQuery.equalTo("status", 1);
userQuery.equalTo("gender", !currentUser.get("gender"));
userQuery.notContainedIn("objectId", friendsIds);
userQuery.notEqualTo("extendUserTags", "rejectPaperPlane");
userQuery.lessThan("paperPlaneProperty_even", 5);
userQuery.greaterThan("lastActTime", new Date(now.setMinutes(now.getMinutes() - 10)));

userQuery.skip(10);
userQuery.limit(5);
userQuery.find();

比如说：

额 在这之前 报了很多超时错误的。但是今天之后就没有了。如下图，这是记录到的最后几条查询超时问题。

有可能，谢谢啦。

但是又继续有了。。。

已经好得多了。不过还是有一些。这个问题只能通过建立索引来解决么。

不能把建立索引的功能接口开放出来给我们用么？
感觉每次要建立索引都要麻烦你们，不太方便啊。

但是没有办法做普通索引啊。现在能自主创建的索引都是唯一索引。

好的 感谢
