rss feeds by search term

Thanks xwero,
You got my point. I was thinking in that direction but your suggestion is a little be different.
This is what I was thinking:
A user enters a search term
My code should use the search text and run through all the feeds and return all reults that match the term
But my concern is that unless I have a good feed aggregator, it will require different implementation for each feed. Do you know of any feeds agreegator that supports keywords
