The Expression type exposes the following members.

Methods

	Name	Description
	All	Creates criterion to find all messages.
	And	Creates conjunction between expressions (AND).
	Bcc	Creates criterion to find messages that contain the specified string in the envelope structure's BCC field.
	Before	Creates criterion to find messages whose internal date (disregarding time and timezone) is earlier than the specified date.
	Body	Creates criterion to find messages that contain the specified string in the body of the message.
	Cc	Creates criterion to find messages that contain the specified string in the envelope structure's CC field.
	From	Creates criterion to find messages that contain the specified string in the envelope structure's FROM field.
	GmailLabel	Creates criterion to find messages with specified Gmail label (X-GM-LABELS). This method can be used only if server advertises XGMailExtensions1 extension support.
	GmailMessageId	Creates criterion to find messages with specified Gmail message id (X-GM-MSGID). This method can be used only if server advertises XGMailExtensions1 extension support.
	GmailRawSearch	Creates criterion to find messages with specified Gmail thread id (X-GM-THRID). This method can be used only if server advertises XGMailExtensions1 extension support.
	GmailThreadId	Creates criterion to find messages with specified Gmail thread id (X-GM-THRID). This method can be used only if server advertises XGMailExtensions1 extension support.
	HasFlag	Creates criterion to find messages that have specified flag set.
	HasKeyword	Creates criterion to find messages with the specified keyword flag set.
	Header	Creates criterion to find messages that have a header with the specified field-name (as defined in [RFC-2822]) and that contains the specified string in the text of the header (what comes after the colon). If the string to search is zero-length, this matches all messages that have a header line with the specified field-name regardless of the contents.
	Larger	Creates criterion to find messages with an [RFC-2822] size larger than the specified number of octets.
	Not	Creates criterion to find messages that do not match the specified search key.
	On	Creates criterion to find messages whose internal date (disregarding time and timezone) is within the specified date. In other words, "ON 13-APR-2000" means messages with an INTERNALDATE text which starts with "13-APR-2000", even if timezone differential from the local timezone is sufficient to move that INTERNALDATE into the previous or next day.
	Or	Creates disjunction between two expressions (OR).
	SentBefore	Creates criterion to find messages whose [RFC-2822] Date: header (disregarding time and timezone) is earlier than the specified date.

	SentSince	Creates criterion to find messages whose [RFC-2822] Date: header (disregarding time and timezone) is within or later than the specified date.
	Since	Creates criterion to find messages whose internal date (disregarding time and timezone) is within or later than the specified date.
