�searcher_stringa-This is a plain string search helper for the spawn.expect_any() method.
    This helper class is for speed. For more powerful regex patterns
    see the helper class, searcher_re.

    Attributes:

        eof_index     - index of EOF, or -1
        timeout_index - index of TIMEOUT, or -1

    After a successful match by the search() method the following attributes
    are available:

        start - index into the buffer, first byte of match
        end   - index into the buffer, first byte after match
        match - the matching string itself

|_||_|jt|j�|_|	S)a�This searches 'buffer' for the first occurrence of one of the search
        strings.  'freshlen' must indicate the number of bytes at the end of
        'buffer' which have not been searched before. It helps to avoid
        searching the same, possibly big, buffer over and over again.

        See class spawn for the 'searchwindowsize' argument.

        If there is a match this returns the index of that string, and sets
        'start', 'end' and 'match'. Otherwise, this returns -1. Nrr)rMr�findrrr)r

�searcher_reaVThis is regular expression string search helper for the

    Attributes:

        start - index into the buffer, first byte of match
        end   - index into the buffer, first byte after match
