推荐答案

您应使用MongoDB $ in 运算符-

You should use the MongoDB $in operator -

mongoose.find({title: {$in: ['some title', 'some other title']}})

您向 $ in 运算符提供一个数组，它将返回所有在指定数组中具有确切标题的文档.

You provide an array to $in operator and it will return all the documents which have an exact title in the array specified.
