The first one i try, but not success.
So i try the second link , this time it works perfectly.
this is how i did as instructed .
i open a terminal and paste the following command
cd wget http://advanced-find.googlecode.com/files/advanced_find-0.5.1.tar.gz tar -xvf advanced_find-0.5.1.tar.gz cd advanced_find-0.5.1 ./install.sh
next it ask me for my password.
then i open gedit and go to Edit/Preference/Plugins and select the Adcance/Replace plugin
that is it. i am done.
