Easily search through all blogs into your WordPress MU posts by post title, post content or post author. 
WPMU Global Search can manage multiple search forms. Currently in the following languages:
<ul>
<li>English</li>
<li>Spanish (es_ES)</li>
</ul>
If you have created your own language pack, or have an update of an existing one, you can send <a href="https://codex.wordpress.org/Translating_WordPress" rel="nofollow ugc">gettext .po and .mo files</a> to me so that I can bundle it into WPMU Global Search.

With this plugin, you can create your own variables and use them in WordPress site. It is much more convenient when you update your variables. For example, your contact phone number displays in four places on your site. When you need to update your phone number, you have to find each of them and edit them one by one. With this plugin, you only need to edit it once at the control panel. You can put the shortcode anywhere on your website.

Custom Variables
