OData query $filter conditions and case-sensitivity

Question

Does OData specify whether filter conditions on string fields are to be evaluated case-sensitively or case-insensitively?

Example: (from the docs)

/S         


        

Answer 1

It is now possible to do case insensitive compare by setting EnableCaseInsensitive = true on the ODataUriResolver. I used this with Microsoft.AspNetCore.OData 7.1.0.

     var oDataUriParser = new ODataUriParser(model, uri)
     {
        Resolver = new ODataUriResolver { EnableCaseInsensitive = true}
     };
