 			<li>In <span class="version">v2.20.0</span>, the anyMatch filter can target specific columns using the following format:
-				<pre class="prettyprint lang-js">#:{query}</pre>
+				<pre class="prettyprint lang-js">{column}:{query}</pre>

-					<li>where <code>#</code> is the column <strong>one-based index</strong> (non-developers count from one)</li>

 					<li>and <code>{query}</code> is the specific column query.</li>
 				</ul>
 				<br>
 				You can disable this type of search by setting the new <code>filter_columnAnyMatch</code> option to <code>false</code>.

+					<li>This column specific anyMatch does not support using an OR column search like <code>1:5|7:12</code>.</li>
+					<li><button type="button" data-column="all">name:e</button> Find names (First AND Last) that contain an "e". This searches <em>both</em> name columns, so it is essentially the same as using <button type="button" data-column="all">first:e && last:e</button>.
