Range Filter Evaluation Rectification
Problem : Range Expression filter evaluation is unable to retreive correct
output.
Analysis : Range Filter Expression evaluation is unable to filter out
correct values when the filter values are not present in the data. The Binary
Search method always returns a value greater than the compared value being
passed to it and the value doesn't match in the list.
For Less Than and Greater than condition the non macthing return value
should be adjusted accordingly.
Fix : Fix the value which is being returned from the binary search method
whenever the compared values doesnt match any data in the list.
