If you are looking for arange of numbers and the search is actually set as
number search, you must use the search string in
square brackets, e.g. D=[10-14]
. If you use the brackets
omit, a textual search will be performed.
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]
[10-20 mm] 30[mm] [10 mm]
