I'm creating a custom function (extends ValueSource). I'm generating a value that will both be returned as a value in the hit for each doc and also be used to sort. As I read the documentation, this is not difficult.
To determine the value for a document, I need to access the "stored" fields for that document (i.e., the value that the function will generate partially depends on stored information in the document). How do I access them from the getValues() method? Is this via the FieldCache.DEFAULT? I'm using solr 4.8 if that makes a difference (which I think it does since older examples seem to have been deprecated). For example, if I have a field called "Fred", how do I access that field from the document? Is accessing the stored data going to have a big impact on the time to return results? Thanks Scott
