1    /IGNORE_CASE

    Specifies that searches for strings are not to be case-specific.
    (By default, searches look for an exact match.) This qualifier is
    ignored for value searches.

2    /LENGTH

       /LENGTH={QUADWORD | LONGWORD | WORD | BYTE}

    Specifies the size of the expression value that the SEARCH
    command uses for matching. If you do not specify the /LENGTH
    qualifier, the SEARCH command uses a longword length by default.
    This qualifier is ignored for string searches.

3    /MASK

       /MASK=n

    Allows the SEARCH command finer qranularity in its matches.
    It compares only the given bits of a byte, word, longword, or
    quadword. To compare bits when matching, you set the bits in the
    mask; to ignore bits when matching, you clear the bits in the
    mask. This qualifier is ignored for string searches.

4    /PHYSICAL

    Specifies that the addresses used to define the range of
    locations to be searched are physical addresses.

5    /STEPS

       /STEPS = {QUADWORD | LONGWORD | WORD | BYTE | value}

    Specifies the step factor of the search through the specified
    memory range. After the SEARCH command has performed the
    comparison between the value of expression or the given string
    and memory location, it adds the specified step factor to the
    address of the memory location. The resulting location is the
    next location to undergo the comparison. If you do not specify
    the /STEPS qualifier, the SEARCH command uses a step factor of
    a longword for value searches, and a step factor of a byte for
    string searches.
