Hardy,
Starting from your last point and moving backward, I guess that's the point – all that has to happen is for the FacetManager or the search to have to handle two requests at the same time.

I can look at extracting a test case, but I"ll be honest, I'm not exactly sure how to best do that for you. Sounds like I need to write a small application using Hibernate and Hibernate Search that loads thousands of objects into a table and then sets up two threads to perform different faceted searches simultaneously. I can definitely do that ... but I wonder if there might be some test fixtures in place that might be more conducive? Not trying to be argumentative, just trying to be proactive in using everyone's time here.

thanks,

adam
