Symptoms

Testing of Customer Center has shown significant performance issues with the search on Account Number function.
The SQL used to search on account number uses a to_lower() function which results in a full table scan of account_t table. This takes > 10 minutes with their volume of customer data.
Requesting a ability to do a case insensitive search or provision of a configuration item that allows them to disable the to_lower.
The search functionality works fine in our current 7.0 system.
