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.
