Mikhail Khludnev has replied and explained why timeAllowed isn't stopping the query and returning partial results. A 14GB heap is quite large. If you aren't starting Solr with garbage collection tuning parameters, long GC pauses *will* be happening, and that will make some of your queries take a really long time. The wiki page I sent has a section about garbage collection and a link showing the GC tuning parameters that I use. You didn't indicate how much total RAM you have. If your total RAM is 16GB, that's definitely not enough for a 14GB heap and a 40GB index. 32GB of total RAM might be enough, but it also might not be. A "perfect world" RAM size for this setup would be at least 54GB -- the total of heap plus index size, not counting the small number of megabytes that the OS and its basic services take. Thanks, Shawn
