Note: Elementary os luna is still in development and will have many bugs still to be resolved. So these types of issues may occur. This is not to blame the developers but I hope it will be helpful to some body who is using it and has been affected by this issue.
I'm using the daily builds of elementary os luna. I use terminal a lot and uses many command line and terminal shortcuts daily to make my jobs easier. One of such command line short cut is uing Ctr+r to search for the previously used commands. But elementary luna it was not working after I have restarted my computer or even in another terminal. I did a bit of research and found out the issue and fixed it.
