First, thanks again for Lift, we're using it in production now (at http://rhrealitycheck.org) and have received a lot of positive feedback from our audience and content creators.
Had some strange behavior after updating to 1.4 today. Search was only returning posts before about 2009. I reverted back to 1.3 and the results were again displayed as expected. I'm guessing it had something to do with our site in particular since that behavior wouldn't have passed testing.
The only thing I can think of right now that makes content on our site before 2009 different than content after 2009 was the addition of a two taxonomies that no posts before it have and all after do. Do you guys have any ideas why that might have happened?
I updated our staging site to 1.4 so you can see the behavior here:
