I was looking for a couple of threads from last year, but the search function is only showing threads starting in 2016. Did something change? Is there a new setting?
It doesn’t seem like it to me. Are you sure you’re using search terms that will pull up the threads you were thinking of?
Make sure when you go into “Advanced Search” that the “Find Posts From” option is set to “Any Date”. That would be the only thing I can think of.
I tried a quick search for “overpass” - 20 pages of results dating back to 2008. Looks like it still work as expected!
Search does indeed seem to go back a lot farther than 1 Jan. However, search is limited to 500 items (20 pages of 25 items). Searching for “RoboRIO” didn’t get me back into 2015. Could this be your issue?
