- * Revision 1.15 1998/03/05 08:45:14 adam
- * New result set model and modular ranking system. Moved towards
- * descent server API. System information stored as "SGML" records.
- *
- * Revision 1.14 1998/02/10 16:39:15 adam
- * Minor change.
- *
- * Revision 1.13 1998/02/10 12:03:06 adam

- *
- * Revision 1.10 1995/10/30 15:08:08 adam
- * Bug fixes.
- *
- * Revision 1.9 1995/10/17 18:02:14 adam
- * New feature: databases. Implemented as prefix to words in dictionary.
- *
- * Revision 1.8 1995/10/10 13:59:25 adam
- * Function rset_open changed its wflag parameter to general flags.
- *
- * Revision 1.7 1995/10/06 14:38:01 adam
- * New result set method: r_score.
- * Local no (sysno) and score is transferred to retrieveCtrl.
- *
- * Revision 1.6 1995/09/28 09:19:49 adam
- * xfree/xmalloc used everywhere.
- * Extract/retrieve method seems to work for text records.
- *
- * Revision 1.5 1995/09/27 16:17:32 adam
- * More work on retrieve.
- *
- * Revision 1.4 1995/09/07 13:58:36 adam
- * New parameter: result-set file descriptor (RSFD) to support multiple
- * positions within the same result-set.
- * Boolean operators: and, or, not implemented.
- * Result-set references.
- *
- * Revision 1.3 1995/09/06 16:11:19 adam
