<p>When using <ahref="/method/messages.search">messages.search</a> or <ahref="/method/messages.searchGlobal">messages.searchGlobal</a>, a certain message filter may be applied.<br>
This allows the server to filter messages based on a text query, and even on their type, and this feature is often used by graphical clients to implement features like the chat gallery, chat profile pictures and more.
Available filters:</p>
<ul>
<li><ahref="/constructor/inputMessagesFilterPhotos">inputMessagesFilterPhotos</a> - Returns only photos, used for implementing the chat photo gallery, and when scrolling left or right while viewing a photo</li>

<p>The returned <ahref="/type/messages.Messages">messages.Messages</a> constructors contain parameters for <ahref="/api/offsets">pagination</a>, the messages themselves and two <code>offset_id_offset</code>/<code>count</code> parameters that can be used to display a <code>progress/total</code> counter like <code>photo 134 of 200</code>.<br>
For example, when displaying the chat photo gallery, we could display a <code>photo ${offset_id_offset} of ${count}</code> indicator on top.</p>

<ul>

<p>Initially, the tab should be populated with the results returned by passing an empty string in <code>q</code>. </p>
<p>Searching should invoke <ahref="/method/messages.searchGlobal">messages.searchGlobal</a> with the <ahref="/constructor/inputMessagesFilterUrl">inputMessagesFilterUrl</a> filter, rendering the results as specified in the <ahref="#chats-tab">chats tab</a>. </p>

<p>The special <ahref="/method/channels.searchPosts">channels.searchPosts</a> method may be used to globally search for posts from public channels (<em>including</em> those we aren't a member of) and stories from public users, channels and groups (<em>including</em> non-contacts and peers we've never seen before), containing a specific hashtag (which should be passed in the <code>hashtag</code> field without the <code>#</code>). </p>
<p>See <ahref="/api/stories#searching-stories">here»</a> for more info on global search for <em>stories</em> (which should <em>not</em> be triggered when using the global search bar, but rather only when clicking on story hashtags and location tags).</p></div>
