On the code, you can see it is the standard search grid approach.

But when you try to catch the generated code from sql profiler, you can see on the WHERE clause that it is wrapping the strPeriod field within a LOWER function. It runs very slow and causing the error above. It is actually a timeout error.

If you try to tweak the same query and use a straight-forward where clause, the data is retrieved almost immediately.

*Expected:*
Do not wrap the string fields within a {{LOWER}} or {{UPPER}} function.
The i21 standard collation for SQL string fields is {color:#000000}Latin1_Gener{color}{color:#000000}al_CI_AS{color}. Since it is case-insensitive, there is no need for the lower or upper function.
