- * Revision 1.10 1998-09-22 10:03:42 adam
- * Changed result sets to be persistent in the sense that they can
- * be re-searched if needed.
- * Fixed memory leak in rsm_or.
- *
- * Revision 1.9 1998/09/02 13:53:17 adam
- * Extra parameter decode added to search routines to implement
- * persistent queries.
- *

- * Minor changes.
- *
- * Revision 1.7 1998/06/24 12:16:13 adam
- * Support for relations on text operands. Open range support in
- * DFA module (i.e. [-j], [g-]).
- *
- * Revision 1.6 1998/06/22 11:36:47 adam
- * Added authentication check facility to zebra.
- *
- * Revision 1.5 1998/06/13 00:14:08 adam
- * Minor changes.
- *
- * Revision 1.4 1998/06/12 12:22:12 adam
- * Work on Zebra API.
- *
- * Revision 1.3 1998/05/27 16:57:44 adam
