Thanks for that information. You've done a considerable amount of research on the Search function. On several occasions in the past, I experienced an issue with the box locking up after repeated use of Search. I surmised it may have been due to Search not doing a good job of releasing memory. I would suggest rebooting after you experience the issues you described and see if that makes a difference.
I did lots of rebooting (by disconnecting the box from electrical power) while investigating the issue ... and had Technical Support do a download/reboot ... all to no avail.
