Sorting fields while searching!

[vanshi <ni...@gmail.com>]

I have two fields initialized following way for Index writing:

FIRST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED),
LAST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED),

I have a prefix query to look for any name starting with the name entered by
the user. Lets say user enters 'kar' as FName and 'johns' as last name and
then the prefix query becomes 'kar*' 'johns*'. I need to display result in
alphabatical order....that means 'kara johns' must come before 'karen
johns'. First I thought, prefix query itself will rank document with the
alphabatical order but that does not seem the case. So, now I'm trying to
sort while searching, with this code.....but I don't see any difference
between wht the results were before and what they are now. 

sorts.add(new SortField(PhysicianFieldInfo.FIRST_NAME_EXACT.toString(),
SortField.STRING ));
sorts.add(new SortField(PhysicianFieldInfo.LAST_NAME_EXACT.toString(),
SortField.STRING ));

After these 2 sorting, I'm also doing sorting on some other fields but i
guess the name sorting should take precedence over later sortings. Can
anybody suggest what I'm doing wrong here?

Thanks,
Vanshi

It's really unclear to me what
PhysicianFieldInfo.FIRST_NAME_EXACT.toString()
returns. I assume the intent is to return a field name, but
how that relates to
FIRST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED)

doesn't mean anything to me. Could you provide some details?

Note that if you specify a sort field that isn't in the document it
has no effect (i.e. if your
PhysicianFieldInfo.FIRST_NAME_EXACT.toString()
returns something like "2309884@").

I'll ask the dumb question: you *are* passing your
sort object(s) to the search, right?

Finally, take some care about capitalization. My memory is weak,
so check that your casing on the sort fields isn't messing you up.
I'd think about lower or upper case everything you expect to sort on
when indexing since you're not displaying it anyway.....
