How to Query json String in Mongodb

  mongodb, question

The background of the project is to distribute data with the three-party platform. To ensure the data can be traced back, the message (Json format string) under the three-party platform is stored under the Message.bizData node. The sample is as follows. Now I want to query the data of transOrderCode= 91011081818. How should I write the query statement? I tried find (“”message.bizdata.transordercode “:”91011081818 “}) but it didn’t work. Should i deserialize the message into objecjt before storing it into bizData?

Simply put, there is no way to inquire. Because this is a string.
Deserialization into Object allows you to query, but the query uses a full table scan and the performance is very low. It is very important to establish relevant indexes.
