Uwe Schindler commented on SOLR-940:
------------------------------------
bq. I'm also not very familiar with that code in QueryComponent but I guess
that is executed only when field-sort-values are requested (for distributed
search). I wrote tests for sorting and it works fine! So I think the problem
will only be during Distributed Search. I'll modify TestDistributedSearch to
test sorting of trie fields to be sure. If it doesn't, I'll open another issue
to replace the deprecated ScoreDocComparator with FieldComparator.
OK. If distributed search does not work, the problems are bigger: The problem
is not the comparator alone, the problem is the FieldCache. The distributed
search should fill the values into FieldCache and then let the comparator do
the work. Comparing lucenes code with the solr ones shows, that there are some
parts of LUCENE-1478 missing. The Comparators use the default parser instead of
the one given in SortField.getParser() to parse the values (when retrieving
FieldCache.getInts() & Co).
I am not really sure, why Solr needs to duplicate the sorting code from Lucene?
Maybe this is no longer needed? In this case, everything would be ok when
removed.
