Search field form not supporting integers ?

I have a column with integers that I want to show on the form. In the corresponding search field I want to use the 'Greater than' (>) or 'Smaller than (<) sign. Is that not supported ?

You can add an integer field as a search field as type Text box then set the comparison operator to greater than. less than etc. The system does not treat the input as a text string, but correctly compares the integer values.
