I'm looking for a simple note management software , support searching article by title , any recommendations ?
Best not KDE's.
Use Tomboy 
, a very good notes management software
Tomboy is a free and open-source desktop notetaking application written for Unix-like (including Mac OS X and Linux) and Microsoft Windows operating systems, written in C# using Gtk#. Tomboy is part of the GNOME desktop environment, often for personal information management. Its interface is a notepad with a wiki-like linking system to connect notes together. Words in the note body that match extant note titles become hyperlinks automatically, making it simple to construct a personal wiki.
