LXDE customize main menu add SEARCH BOX like in KDE Kickoff or Windows 7/Vista

view story

http://unix.stackexchange.com – When you open the main menu in say MS Windows (7/Vista) you can quickly search for any item (apps/docs etc.) the same in Ubuntu (Dash), Kubuntu (Kickoff menu). Is there any easy way to add such a search input which can filter apps (at least just apps no need for docs) in LXDE's main menu? I Google'd a lot with no success, that's why I'm here. I am a technical person so if you can give even more low level guide's would help (may be I should create some widget custom panel etc.) (HowTos)
