Hey Shinn,

Attached is a fix for the missing search bar in assigning members to a user groups.  This issue can be found at http://issues.liferay.com/browse/LPS-33184.

NOTE: There is currently an issue with the advanced search not working for this search bar.  Can you take a look?  

Please let me know if you have any questions.
