What's the class type of the double?  Older style SortableDouble had
to use the string index.  Newer style trie-double based should use a
double[].

It also matters what the FieldCache entry is being used for... certain
things like faceting on single valued fields still use the
StringIndex.  I believe the stats component does too.  Sorting and
function queries should work as expected.

Oh, forgot to add (just to keep the thread complete), the field is being
used for a sort, so it was able to use TrieDoubleField.

Thanks again,

Re: Sort fields all look Strings in field cache, no matter schema type

This field is of class type solr.SortableDoubleField.

I'm actually migrating a project from Solr 1.1 to 1.4, and am in the process
of trying to update the schema and solrconfig in stages. Updating the field
to TrieDoubleField w/ precisionStep=0 definitely helped.

Thanks Yonik!
