I'm doing some testing with the Google+ Search API, and it seems like it's completely broken. Can anyone else confirm?
Try searching for something popular using the Google+ API, ordered by recent. Here's a test for 'iphone'. For me, the most recent result was 25 minutes ago. (Your results may vary, depending on time.)
Now, do the same search on Google+ itself, and click the "Most recent" link to only show recent posts.
At first, Google+ shows the same sparse results of relatively outdated posts... Then, slowly, it populates with newer posts from the last couple minutes.
Unfortunately, I can't figure out a way for the Google+ API to show those newer posts. Any help? Any Googlers out there able to help out?
