   *  DIS Data Management: query
   *
   *      This header file contains the return codes for the query routine 
   *      and the function prototype.  There are two different failure modes for
   *      the routine.  The first indicates that the search index key passed as 
   *      input to the routine is invalid.  The second indicates that the 
   *      attribute code specifying which non-key attribute to search on is 
   *      invalid (too small or too large).
