   I want to be able to provide an RSS feed based on a word that people may be interested in -- something similar to Google Alerts.

   I've checked over a few plug-ins including Extra Feed Links and Feed Wrangler but the most I seem to be able to do is produce an RSS feed based on a tag or category, which would mean a lot of extra work having to re-tag all my posts based on what people might wish to get by RSS some time in the future.

   Does anyone know of a specific plug-in which can do this, or how I can customize say Feed Wrangler to do this?

   I now have a solution based on Feed Wrangler, although it's probably not very elegant.

   I duplicated wp-rss2.php as feed-news.php and added the code

   $keyword = $_GET['keyword'];
   $keyword_cap = ucwords($keyword);

   into the top of the file.

   Immediately after the <description> tag I added

   <?php echo $keyword_cap; ?>

   and after

   <?php while( have_posts()) : the_post(); ?>

   I added

   <?php if(strstr(strtolower(get_the_content()), $keyword )) : ?>

   closing the whole thing with

   <?php endif; ?>

   placed immediately before

   <?php endwhile; ?>

   Now, by using the feed http://www.mysite.co.uk/news/?keyword=keyword I get an RSS feed for whatever keyword I use providing, of course, that the keyword appears in the posts.

   One other thing; I upped the number of feed posts displayed in WordPress's settings to 200.

   Seems to work fine.

   You should just use the search feed instead: http://example.com?s=keyword&feed=rss
