: In my schema.xml, I have these copyFields: you haven't shown us the field/fieldType definitions for any of those fields, so it's possible "simplex" was included in a field that is indexed=true but not stored-false -- which is why you might be able to search on it, but not see it in the fields returned in a search.
Wild guess... : <copyField source="body" dest="alltext" /> ...perhaps your "body" field is stored=false, but contains "simplex" and was copied into alltext. -Hoss http://www.lucidworks.com/
