8851e10017 Do not do the optimization that attempts to pull expression values from 
an index on that expression when processing a multi-index OR
(see check-in [a47efb7c8520a0111]) because the expression transformations
that are applied become invalid when the processing moves off of the current
index and on to the next index.  Fix for ticket [4e8e4857d32d401f].
