    make 'and' operator work on multiple-term arguments
    
    Currently the query generated by the numeric handler only
    generates a correct SQL statement for 'or' operators when
    working with mulitple-term arguments (e.g. /myview/2+3+4)
    but does not work with the 'and' operator (/myview/2,3,4).
    
    This patch adds a HAVING clause to the 'and' queries that
    requires that all of the terms matched in the 'IN' where
    clause are matched.
