How to search for content from the Content Management admin view?
In drupal 7 you can use the Aministration Views. 

It uses the Views module and VBO to create some views to replace all the pages in administrtion area that does some kind of listing.

After the instalation you need enable the views created by this module.

For me this was the only way to get a "Title filter" for the contents in the drupal administration area.
