I was using hnrss.org to create an rss feed for hacker news filtered on posts with more than 75 points. I noticed (not sure when this happened) that the search stopped working. I then deleted and re-added the rss feed. The initial pull of data from the feed gets 10 stories and search works. The number of stories stays at 10 however. If I go to Site Settings and tell newsblur to manually parse the rss/xml feed, I get all the stories I would expect, but then search stops working again (tried this multiple times with same behavior). However, if I create a feed filtered on posts with 50 or 100 points, everything works as expected. I tried the same thing with hnapp.com and get the same behavior with regards to 50,75, and 100 points. Any ideas on what the issue could be?
The address for the feed is: http://hnrss.org/newest?points=75
One other thing I noticed is that the number of subscribers listed for the hnrss feed filtered on 50 and 100 points is the same, whereas for the feed filtered on 75 alternates between -1 and 5.
