Wordpress keyword search and tag insert

I am looking for a way to search ALL of my Wordpress posts for a 'Keyword' or 'Keyphrase'. If found within a post then I want to automatically post a TAG automatically to that post without having to manually edit an individual post.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You should be able to do this via the All Posts and Bulk Edit functions in the WordPress admin interface.

Go to Posts | All Posts, use the search on the right side of the screen to search for your word or phrase.  Select all posts that come up in the results and use Bulk Edit to add the desired tag.

OM, that works. That was worth the annual subscription price to Experts Exchange to find that this simple approach exists. Thank you! Thank you! There are probably 99 other things that I don't know about WP even though I have been a heavy user for several years now.
