We have discovered another problem - we are not sure what version it was introduced but we are attempting to find out.
In a recent post I stated that we went from version 1.9.5 (i wish they would show it as 05) to 1.9.14 and ADFS started failing, now we've discovered that our Goggle search results are also not working correctly.
Instead of the Title and snippet fields containing the http title and meta name "description" information, what we are seeing is the Tile appears to be the date & time of the crawl and the snippet looks like the response header. I've been looking through the change logs but I honestly can see anything that might be causing this. There was one thing in 1.9.07 Feature: the "proxy_cache_convert_head" directive. that might be it but it's off by default.
Any ideas would be helpful. We are going to start trying different versions to see if we can pinpoint where it started to occur. We are starting a test at version 1.9.10 at this time. Will keep updating as we determine more.
