ZyFIND crashes when performing @@docs() search in a large (200K - 300K documents) index.
ZyFIND is a 32-bit application and can only make use of so much memory.
While the memory used by ZyFIND was increased from 1.6GB to 3GB in version 6.5, there is a limit to how much can be done with a 32-bit application. Advise to limit searches to smaller document sets.
6.4, 6.5, 6.6
