The following flag means that buffer with a string (document, word)
may be overwritten by the caller before the end of the parsing (that is
before st_mysql_ftparser::deinit() call). If one needs the string
to survive between two successive calls of the parsing function, she
needs to save a copy of it. The flag may be set by MySQL before calling
st_mysql_ftparser::parse(), or it may be set by a plugin before calling
st_mysql_ftparser_param::mysql_parse() or
