Subject OutOfMemory error while sorting
Date Wed, 14 Jun 2006 10:25:45 GMT

I have a new problem with OutOfMemory errors.
As I reported before, we have an index with more than 10 million 
documents and 23 fields. Recently I added a new field which we will only 
use for sorting purposes (by "adding" I mean building a new index). But 
it turned out that every query using this field for sorting ends in an 
out of memory error. Even sorting result sets containing just one 
document does not work. The field is of type solr.StrField and strange 
enough there are some other fields in the index of the same type which 
do not cause these problems (but not all of them; our uniqueKey-field 
has the same problems with sorting).
Now I am wondering why sorting works with some of the fields but not 
with others. Could it be that this depends on the content?
