If min or max index values was truncated, a comparison of the actual
indexed field value (i.e., primary table value) is done with the min and/or max values.
@param f index field from index table iterator
@return true if field value corresponding to f is outside the min/max range.
It is assumed that the underlying table iterator will not return index values
out of range which do not have the same truncated index value.
@throws IOException thrown if IO error occurs
