I just installed lxde to boot into when laptop is using battery, but I really miss at least a simple search feature, I am used to Unity so I find myself losing too much time navigating on the menus, given that the LXDE menu is just a list with a basic categorization. I would prefer to avoid creating shortcuts everywhere if possible.

Forget about that, there's nothing like that for the LXDE menu, use Synapse.

Install it from the terminal: sudo apt-get install synapse

Synapse review with screenshots

The correct, fancy name for it is semantic launcher BTW :)

Other related stuff:
Zeitgeist - indexing tool used by Synapse
Gnome Do - another launcher similar to Synapse, older

Thanks, Synapse will do the job :) – Neptunno Oct 21 '12 at 0:18
I can't find it in the repositories now. Is it discontinued or what? – Mina Michael Jul 28 '14 at 19:26
it sounds kinda heavyweight. will it run ok on old hardware (the reason i'm running lubuntu/lxde)? – hwjp Nov 26 '14 at 13:26
You have to add a PPA to run synapse on Ubuntu 15.04: – rubo77 May 17 '15 at 0:20

XFCE provides an excellent app finder. You can install it with

sudo apt-get install xfce4-appfinder

Kupfer provides a simple menu searcher activated from a global keyboard shortcut.

sudo apt-get install kupfer

By default you show Kupfer using the global keyboard shortcut Ctrl+Space.
