Question

Each row has a title and description.

I created an RSS feed which gives you the latest entri

Answer 1

I would go with JohnB's or gtr32x's answer (Full Text Indexing). To complement their answer, there's a manual way to create a simple full text index that's simple and it's super fast...

Split title and description into keywords, and place them in a Keywords table, which has a foreign key to the original RSS article. Make sure the keyword column in Keywords is indexed. The you can do something like:

SELECT DISTINCT ra.* 
FROM RssArticle ra
INNER JOIN Keywords k ON k.ArticleID = ra.ArticleID
   WHERE k IN ( 'SearchTerm1', 'SearchTerm2', 'SearchTerm3')
LIMIT 20;

And it's fast!
