Erik:
doc.add(Field.Keyword("rank_field", rank_value));
is what I use to build my customized rank field.
Considering the rank_value is an integer, should it be zero padded?
Currently I have it padded because the rest of lucene needs it that
way, should it be the same here?
If I specify INT or STRING, the sort of rank works just fine... but
its when I combine the two that I have issues. I'm using 1.4.2... but
I'll see how my code differs from yours and give it a try.. can you
tell me how you indexed your secondary rank field? as a keyword or
what have you?
Thanks,
Chris Fraschetti
