The PD completion-plugin adds auto completion and object searching functionality to PD vanilla!
I've just updated the plugin and uploaded it in Deken!
Just search for "completion".
See the full readme (gif included) on Git Hub:

The plugin is reportedly working on Win, Linux (tested on Ubuntu) and OS X.
Raspberry Pi testers needed!
Cheers
