I work at a coalition and am trying to collate specific news information from our city site:

On the website, there are category-specific boxes to check to show a narrowed range of articles. For instance, if I want to only look at articles pertaining to the Alameda Neighborhood, I click the box and only show the small amount of articles written that involve that neighborhood. The new URL looks like this:

When I try to pull the RSS feed from the URL over to WordPress, the changes don't show up. I can only pull an RSS feed that shows every article written. I tried using RSS.app to try to have it aggregate based on the different URLs and the feed does change based on the URL when I use that service. Why does the different URL work with the RSS.app but not when I directly use the different URLs in the RSS block in WordPress?
