+ * New method result set method rs_hits that returns the number of
+ * hits in result-set (if known). The ranked result set returns real
+ * number of hits but only when not combined with other operands.
+ *
+ * Revision 1.22 1997/10/31 12:38:12 adam
+ * Bug fix: added missing xfree() call.
+ *
+ * Revision 1.21 1997/09/17 12:19:23 adam
+ * Zebra version corresponds to YAZ version 1.4.
+ * Changed Zebra server so that it doesn't depend on global common_resource.
+ *
+ * Revision 1.20 1997/09/09 13:38:17 adam
+ * Partial port to WIN95/NT.
+ *
+ * Revision 1.19 1997/09/04 13:58:57 adam
* Added O_BINARY for open calls.
