: 1) Where can I find docs on how to get Solr to feed RSS directly? if you mean "consume rss" you should take a look at the DataImporthandler -- it let's you configure XPath expressions for extracting documents/fields from xml files. If you mean "produce rss" the XSLTResponseWriter can apply a stylesheet server side to generate RSS (that's why the example rss XSLT exists)
: However, how do you handle RSS feeds for indexes where data can be both : added and removed? For example, if I want to have an RSS feed of users on my : site, I want new users to show up as new items in the RSS feed as they come : along. However, users don't stick around forever, they can also disappear : from the database. Similarly, users can change their information and thus : they may not match a particular query anymore (and would thus disappear from : the RSS feed, right?). : Wouldn't this cause havoc for RSS readers if results changed often? This question is a little out of the scope of a Solr discussion. The potential issues you describe with trying to serve data using RSS are going to be something you'll have to consider regardless of wether the RSS is generated from a Solr result, or a database result, or even a flat file on disk that you manually edit by hand. It's all very dependent on what your clients are expecting to see in that feed in each of hte situations (delete/edit) that you describe. If you can decide how you *want* the resulting feed to look in each of those use cases, you cna probably model the Solr Documents in a way to represent it. -Hoss
