Use filter in find_items

[JLopeDeB]

Ho Plaristote,

Thank you very much fro you gem, it's super useful and the only one for rails, I think.

If possible, could you provide an example of the find_items method using the filter: parameter? I simply want to filter a particular folder name so not all items are returned by the method. Been looking into http://www.odata.org/documentation/odata-version-2-0/uri-conventions/#FilterSystemQueryOption for the right documentation, but is not working as expected. Perhaps an working example will bring some light. Thanks in advance for your help.
