<h2>Detailed Description</h2>
<p>The QMailMessageKey class defines the parameters used for querying a subset of all available messages from the mail store.</p>
<p>A QMailMessageKey is composed of a message property, an optional comparison operator and a comparison value. The QMailMessageKey class is used in conjunction with the <a href="qmailstore.html#queryMessages">QMailStore::queryMessages</a>() and <a href="qmailstore.html#countMessages">QMailStore::countMessages</a>() functions to filter results which meet the criteria defined by the key.</p>
<p>QMailMessageKeys can be combined using the logical operators (&amp;), (|) and (~) to create more refined queries.</p>
<p>For example:</p>
<p>To create a query for all messages sent from &quot;joe@user.com&quot; with subject &quot;meeting&quot;:</p>
<pre>    QMailMessageKey subjectKey(QMailMessageKey::subject(&quot;meeting&quot;));
    QMailMessageKey senderKey(QMailMessageKey::sender(&quot;joe@user.com&quot;));
    QMailMessageIdList results = QMailStore::instance()-&gt;queryMessages(subjectKey &amp; senderKey);</pre>
<p>To query all unread messages from a specific folder:</p>
<pre>    QMailMessageIdList unreadMessagesInFolder(const QMailFolderId&amp; folderId)
    {
        QMailMessageKey parentFolderKey(QMailMessageKey::parentFolderId(folderId));
        QMailMessageKey unreadKey(QMailMessageKey::status(QMailMessage::Read, QMailDataComparator::Excludes));

        return QMailStore::instance()-&gt;queryMessages(parentFolderKey &amp; unreadKey);
    }</pre>
