I do not have long experience with mongoDB, and I was working on this question mongodb - Spring Data Mongo Property Expression Query not returning any results - Stack Overflow
just for the context it is related to using parent child classes in mongodb in java with spring, and at the end MongoRepository is not really querrying if I am trying to query Object->data->Parent->object->id like structure. This is probably would work in RDBMS but as far as I understand mongo can only allow one hop. so one nested object queryable not further.
I answered it as good as I can, but I am not sure about nested field querying still. Can anyone confirm this mongodb - Spring Data Mongo Property Expression Query not returning any results - Stack Overflow ?
