Thx Uwe,

after sleeping over the problem...
The solution just hit me ;)
I index a double for the Numeric field but my Sortfield was setup as a =
float.
(Maybe this is something for a FAQ for NumericFields)

Thx

Uwe

Betreff: RE: Problem with sorting on NumericFields

This happens if your field still contains other value types in this =
field,
maybe from deleted documents. The problem is that even if no document
contains the old field encoding anymore, it could still be leftover =
terms in
terms index. So the FieldCache code loads the terms (even if no longer
documents are attached) and  tries to parse it. So if it was before a
different field type like a conventional plain text encoded numeric, the
parsing of those old terms fails. You should reindex the whole stuff or =
at
least try to optimize the index to get rid of deleted documents and the
terms.
