1    /CONTENT

       /CONTENT=substring
       /ENV_FROM=substring
       /SUBJECT=substring

    The /CONTENT, /ENV_FROM, and /SUBJECT qualifiers are used to
    specify the substrings for which to search. Any combination of
    /CONTENT, /ENV_FROM, and /SUBJECT may be specified. However, only
    one of each may be used. When a combination of such qualifiers
    is used, the /MATCH qualifier controls whether the qualifiers
    are interpreted as further restrictions (/MATCH=AND), or as
    alternatives (/MATCH=OR).

2    /DATABASE

       /DATABASE
       /DIRECTORY_TREE

    Controls whether the message files searched are only those with
    entries in the queue cache database, /DATABASE, or all message
    files actually present in the channel queue directory tree,
    /DIRECTORY_TREE.

    When neither /DATABASE nor /DIRECTORY_TREE is specified, then the
    "view" selected with the VIEW command will be used. If no VIEW
    command has been issued, then /DIRECTORY_TREE is assumed.

3    /DELETE

       /DELETE
       /HOLD (default)

    /HOLD is the default and means that matching message files will
    be held. Specify /DELETE to instead delete matching message
    files.

4    /MATCH

       /MATCH=keyword

    The default is /MATCH=AND, meaning that any criteria specified
    by /CONTENT, /ENV_FROM, and /SUBJECT qualifiers must all match
    in order for the current hold or delete operation to be applied.
    Specifying /MATCH=OR means that a message will match as long as
    at least one such criterion matches.

5    /MIN_LENGTH

       /MIN_LENGTH=n

    By default, each substring to be searched for must be at least 24
    bytes long (/MIN_LENGTH=24). This is a safety measure: the longer
    the substring, the less likely the chance of false "hits". Use
    the /MIN_LENGTH qualifier to override this limit.

6    /THREADS

       /THREADS=n
       /NOTHREADS (default)

    The /THREADS qualifier may be used to accelerate searching on
    multiprocessor systems by dividing the work amongst multiple,
    simultaneously running threads. To run n simultaneous searching
    threads, specify /THREADS=n. The value n must be an integer in
    the range 1-8. The default is /NOTHREADS.

7    /VERBOSE

       /VERBOSE
       /NOVERBOSE (default)

    The /VERBOSE qualifier may be used to request that the utility
    print out information about what it is doing as it operates.
