searching list of words in a cell

[nazaninibb]

Hi every body
I am new to excel.
I have a list of words (983) which I want to be searched within a cell.
I know that it may be a straightforward task. I actually found similar question but the answer could not help me.
I have attached a small part of my excel file.
First column contain list of words and second columns are the cells that must be searched.
I will appreciate any help
