/**
 * Search criteria are expressed as a tree of search-terms, forming
 * a parse-tree for the search expression. <p>
 *
 * Search-terms are represented by this class. This is an abstract
 * class; subclasses implement specific match methods. <p>
 *
 * Search terms are serializable, which allows storing a search term
 * between sessions.
 *
 * <strong>Warning:</strong>
 * Serialized objects of this class may not be compatible with future
 * JavaMail API releases.  The current serialization support is
 * appropriate for short term storage. <p>
 *
 * <strong>Warning:</strong>
 * Search terms that include references to objects of type
 * <code>Message.RecipientType</code> will not be deserialized
 * correctly on JDK 1.1 systems.  While these objects will be deserialized
 * without throwing any exceptions, the resulting objects violate the
 * <i>type-safe enum</i> contract of the <code>Message.RecipientType</code>
 * class.  Proper deserialization of these objects depends on support
 * for the <code>readReplace</code> method, added in JDK 1.2.
