Hi

I have 100k rows with some data in them which are some kind of questions. I want know the most common (single)sets of words in each question. For more clarity about my question please go through this example:-

What is the law of physics?
What is law of thermodynamics in physics?
What is the law of quantum energy in physics?
What is the law of gravity in physics?
Laws of motion in Physics?

In all above rows LAW and PHYSICS is common , so I want a macro that will give me these two words. And of course what, which, why will be their as well so they needs to be neglected. More words like is,are, the, of etc etc.

Is this is possible to do this through macro, if yes then please help me.

Thanks in advance.
