Per-User Sorting on an ExternalFileField

[Phill Tornroth <fa...@gmail.com>]

I'm trying pretty hard to come up with a solution that lets me sort by
per-user scores that I calculate based on my data. Today, I'm trying to use
a combination of ExternalFileField and dynamic fields, where the
presumption is that each user might have their own file full of scores. I
think the fields are hooked up okay, but I can't sort on them because it
appears ExternalFileField explicitly doesn't support this operation.

SEVERE: java.lang.UnsupportedOperationException
at
org.apache.solr.schema.ExternalFileField.getSortField(ExternalFileField.java:91)


I'm using Solr 3.5. Does anyone have a suggestion as to how to end up
adding this extra dimension so that I can do per-user relevance? It seems
like an oft-asked, rarely-answered question.

Thanks in advance,

Phill

So, I did just issue:

   &sort=sub(my_user_score_field,0)+desc

It got me past the error, but still doesn't appear to be actually using the
values to sort. Any ideas as to why?

Use a function that make use of your externalfilefield and alter the score
so that you can sort on the score ?
