Searches appear to be case insensitive. This list of criteria is from a reading of the UW c-client source code and may be incomplete or inaccurate (see also RFC2060, section 6.4.4). Valid values for flags are SE_UID, which causes the returned array to contain UIDs instead of messages sequence numbers. Parameter charset was added in PHP 4.3.3.
