Well, I am using a Sort object ("Hits = Search.search(Query, Filter,
Sort)" actually).
In setting up the SortField array for that Sort object with a
SortComparatorSource the issue comes up that I need to access the
field value that is being used for sorting.
Maybe that's just the way Lucene works, but it seems that there
should be an easy way to get at the field value without having to
retrieve the document from the index.
Cheers,
Ulf

Maybe I'm missing something in turn, but why not just use a Sort
object at
search time? You can have a Hits object or TopFIeldDocs object
returned
(the Filter in some of these calls can be null).

Hello-
One of the fields in my index is an ID, which maps to a full text
description behind the scenes. Now I want to sort the search results
alphabetically according to the description, not the ID. This can be
done via SortComparatorSource and a ScoreDocComparator without
problems. But the code needed to do this is quite complicated - it
involves retrieving the document ID from the ScoreDoc, then looking
up the Document through an IndexReader, and then retrieving the ID
field from the document. It seems that there should be an easier way
to get at the ID field, since that is the one being used for the
sort. There is a related class FieldDoc, through which it seems
possible to get at the field values, but that doesn't seem
applicable here.
I went through the custom sorting example of "Lucene In Action", but
that doesn't deal with this case. Am I missing something obvious?
Thanks in advance,
Ulf
