The PubSub Matchbox
"Making the Most of the Matching Engine"

I’m going to try something new. Every Friday, I will post a tip on how to best use the PubSub service. Today, I focus on the “URI” attribute.

If you wanted to the engine to match any weblog posts that have a link to an mp3 file in it, just put URI:mp3 in your query. In additon, you can limit the results by putting in some keywords. Thus a query for (podcast | podcasting | podcasted) AND URI:mp3 will match results that have the specific keywords AND have a link to an mp3 file.

If there are any PubSub tips that you would like to share, send us a note.
