Need Help to build a news articles database

Hi,
I have a query, the solution of which i am not sure will be in excel or word or some utility website on internet. I am requesting all of you to kindly help me out.

I am creating a database of news articles, which are classified under 5 separate categories.
News Headline - News Body - Date - Source - Link to the Article

I want to create a database such that I can view news articles classified with the "News Headline - Source" arranged chronologically. This I am able to do.

What i am unable to do:
1. When i click on certain headline, it should make available the entire article in readable format(News Body).
2. When i search for certain keywords, it should search for the entire article, not just the headline.
I will update the database from the articles i gather daily. But the process of updating should not be too tedious.

Please suggest if you have something creative in mind

P.S. - Below is a sheet attached which displays the way I do it currently.
