+ * 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 1.12  1997/09/05 15:30:03  adam
  * Changed prototype for chr_map_input - added const.
  * Added support for C++, headers uses extern "C" for public definitions.
