I have a new version out at https://rewardsearcher.ft.canadiancow.com/

It skips AWS API Gateway, so avoids the 29 second timeout. I have this set for 60 now, which should be sufficient for the maximum search size I currently allow.

I'm not going to update the wiki or first post yet, but I'd appreciate if some people can use this instead and let me know if anything is totally broken.
