trie fields and sortMissingLast

Should sortMissingLast param be working on trie-fields?

Is there a good opportunity to work on this issue right now?  I'd be happy to
do it, if you could provide some initial advice on how to attack the
problem.  Moving forward, I'd like to use Trie fields, but the lack of this
option is really holding me back...

Not yet - that info is not available from the lucene FieldCache.

Just curious if there has been any progress on implementing sortMissingLast
on TrieFields?

Eventually.  It's currently not supported though.  Here's the comment
from the example schema.xml:

    <!-- The optional sortMissingLast and sortMissingFirst attributes are
         currently supported on types that are sorted internally as strings.
               This includes
"string","boolean","sint","slong","sfloat","sdouble","pdate"
       - If sortMissingLast="true", then a sort on this field will
cause documents
         without the field to come after documents with the field,
         regardless of the requested sort order (asc or desc).
       - If sortMissingFirst="true", then a sort on this field will
cause documents
         without the field to come before documents with the field,
         regardless of the requested sort order.
       - If sortMissingLast="false" and sortMissingFirst="false" (the default),
         then default lucene sorting will be used which places docs without the
         field first in an ascending sort and last in a descending sort.

Nope, trie fields do not support sortMissingFirst or sortMissingLast.
