Enhance documentation for field names

[ivanjaros]

As I read through the documentation, you are using GOB by default and the field names in queries have upper-case first letter which I think means that the fields used in queries must match the de/serializer. So if one would use json then the field names in queries would be most likely all lower-cased. If this asumption is correct, I think it should be mentioned in the documentation that for queries, one should use field names the serializer uses itself and not struct fields, by default.

That's all determined by the encoding you use. I default to Gob, but you can use any encoding that generates a byte slice.

You specify the encoder in the options when opening a DB: https://github.com/timshannon/badgerhold/blob/master/store.go#L36
