Define relativeorbitnumber with dhusget


I’m trying to bulk-download some images with dhusget. When I define the platform and the product with
-F ‘platformname:Sentinel-1 AND producttype:SLC’ it works, but when I add the relative with
-F ‘platformname:Sentinel-1 AND producttype:SLC AND relativeorbitnumber:117’ it doesn’t retrieve anything.

I’m sure that images with orbit 117 are available on my test site because I checked in open hub website.

Am I doing a sintax error?

Thank you
