How to create a searchable database with a single-field search box at the front end? [closed]

Guess what! I just found what I was looking for and I’d like to share it with you.
There is this newly-developed plugin that meets my needs (as described in my first post) and is fully customizable for other purposes as well. So, if you were also looking for such a solution, look no more! I hope many others would install and use the plugin and rate it high as an appreciation to the author/developer of such a great plugin. Here’s the link:

I think I can now mark the question I’d raised as [resolved] !

Happy using it:)

Cheers!
