If you are searching for a range of numbers and the search is actually to be carried out as a number search, you must enclose the search string in square brackets, e.g. D=[10-14]. If you omit the brackets, a textual search will be carried out.
D=[10-12] [10-20]
Square brackets are already used in the number search with units, so the two options can also be combined.
D=[1-2 inch]
