[KinoSearch] delete_by_term problem?

[Dan]

I can do searches by  "svid:foo" but it does not like me deleting docs by svid..
I think I'm using it correctly...

$invindexer->delete_by_term( svid => $svid);
Invalid parameter: 'svid' at xs/XSBind.c:314 kino_XSBind_allot_params
         at build_index.pl line 54

anyone seen this?
