$top option doesn't work #62
Description
Hello, I'm a Purdue student using the api for my CS 307 software engineering project. I'm trying to implement a searching function for all courses, but I noticed that purdue api doesn't support the $top query option. The problem is if there's too many results it takes a while to load, which stalls the searching. It would be a lot more efficient to use $top and $skip so I can lazy load the results when scrolling down. Is it trivial to implement $top? If you don't have time and it's relatively simple I was thinking I could make a pull request.
Result of this query Courses?$top=10:
{
"error": {
"code": "",
"message": "The query specified in the URI is not valid. The limit of '0' for Top query has been exceeded. The value from the incoming request is '10'.",
"details": [],
"innererror": {
"message": "The limit of '0' for Top query has been exceeded. The value from the incoming request is '10'.",
"type": "Microsoft.OData.ODataException",
"stacktrace": " at Microsoft.AspNetCore.OData.Query.Validator.TopQueryValidator.Validate(TopQueryOption topQueryOption, ODataValidationSettings validationSettings)\n at Microsoft.AspNetCore.OData.Query.Validator.ODataQueryValidator.Validate(ODataQueryOptions options, ODataValidationSettings validationSettings)\n at Microsoft.AspNetCore.OData.Query.EnableQueryAttribute.ValidateQuery(HttpRequest request, ODataQueryOptions queryOptions)\n at Microsoft.AspNetCore.OData.Query.EnableQueryAttribute.OnActionExecuting(ActionExecutingContext actionExecutingContext)"
