“需要由:: \“ path \”引起的mongot ::远程错误来自\“ wildcard \””-mongodb Atlas Search中的错误Java驱动程序

问题描述

当尝试使用mongodb Java驱动程序进行MongoDB Atlas Search 查询时，我得到了以下信息，而我正在使用Java驱动程序4.1。

exception in thread "main" com.mongodb.MongoCommandException: Command Failed with error 8 (UnkNownError): 'Remote error from mongot :: caused by :: "path" is required (from "wildcard")' on server ***. The full response is {"operationTime": {"$timestamp": {"t": 1603099324,"i": 1}},"ok": 0.0,"errmsg": "Remote error from mongot :: caused by :: \"path\" is required (from \"wildcard\")","code": 8,"codeName": "UnkNownError","$clusterTime": {"clusterTime": {"$timestamp": {"t": 1603099324,"signature": ***},"keyId": ***}}}

at com.mongodb.internal.connection.CommandProtocolImpl.execute(CommandProtocolImpl.java:71)

在代码段之后，它是从mogodb Atlas控制台本身生成的。

testingCollection.aggregate(Arrays.asList(
    eq("$search",eq("wildcard",and(
                            eq("path","name"),eq("query","dushan*"),eq("allowAnalyzedField",true)
                       )
              )
      ))).first();

你知道是什么原因吗？
