Numeric Dimensions and Operators

If a condition dimension is compared with a numeric value using the equal (=) operator, then you can improve performance by setting its data type to text. Property sets can store only text values, and when you use a numeric comparison, there is an overhead to convert the text to numeric values at run time. You must use numeric values for less than (<) or greater than (>) comparisons, but if you are using an equal (=) comparison operator, then you will get the same result whether the data is numeric or text.
