: "location_name" is a text field , copyto puts it in "facet.location_name" : : i'm thinking this could be because the field was not entered as NULL but an : empty string ?
assuming "facet.location_name" is a StrField then that would certainly be your problem -- because the empty string is a legitimate string value. i would suggest properly indexing without the empty string value, but i suppose fq=facet.location_name:"" would probably work as well (untested) -Hoss
