Library /sys$common/syshlp/pca$help.hlb SET, SEARCH, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The SET SEARCH command allows you to set the SEARCH command's
    default qualifiers. If you provide two parameters or qualifiers
    that have contradictory actions (such as ALL and NEXT), then the
    latter parameter or qualifier in the sequence is accepted. If
    you provide a qualifier and a parameter that have contradictory
    meanings (such as /ALL and NEXT), then the parameter takes
    precedence. Each of the qualifiers may be expressed as a
    parameter.
