When to use and how to get querying proficiency
Alright, I will try to be short here but anyone let me know if more info is needed. We had this new project started 3 months ago, that was increasing the amount of data it was going inside our Elast...

MicrosoftHey Pedro - I'm not quite sure I understand your third question. Are you trying to select a certain field but the data for it isn't being returned? Are you serializing the data and that's when it becomes null?
- That is correct, in the deserialization process the data end up null.
- DerekLegenzoffThanks for the clarification. The reason that the data is ending up null is because a decision was made that we want customers to own their data models as a best practice so the in-built data types don't necessarily serialize all fields (you'll run into a similar issue with counts on facets). To get around the issue you're running into, I would recommend mapping the data from the response into classes that you create. You can do this pretty quickly with a package like Mapster: https://github.com/MapsterMapper/Mapster
- Derek that sounds very promising, do you have any examples of that? I'm confuse because trough the sdk the only way for me to call the search is to pass a class for it to automatically deserialize the results for me. https://docs.microsoft.com/en-us/dotnet/api/overview/azure/search.documents-readme
so, i'm wondering, how do I control that field mapping conversion myself? Is it trough field mappings with annotations? like the mapster example show? (never seem mapster, seems very interesting, have only used automapper mysef).
