I want to make index as integer

[Michiaki HAMADA / FUJI-RIC]

Hi all,

I want to create index to element ( which date type is defined as the
integer
in schema ) as integer, and to search these elements by range of integer (
for example,
I want to get the elements whose values are more than 10 and less than 20 ).

Please teach me how to do it.

Thanks.

Michi
