/sys$common/syshlp/helplib.hlb SEARCH, Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 filespec[,...]

    Specifies one or more files to be searched. You must specify
    at least one file name. If you specify more than one file name,
    separate the file specifications with commas (,).

    You can use the asterisk (*) and the percent sign (%) wildcard
    characters in the file specification.

 search-string[,...]

    Specifies the character string to be located in the specified
    files. Enclose strings containing lowercase letters, blanks, or
    other nonalphanumeric characters (including spaces) in quotation
    marks (" ").

    You can use the /MATCH and /EXACT qualifiers to alter the way
    that SEARCH matches search strings.
