Why 2 Different JSON Results with String Parameter Search using RestSharp? - json

Question

If I hard code the band name in my client request with RestSharp I get the results I expect. If I pass in the String I get a different result set. I checked the url it formed and they are the same. Any ideas? I don't use both, I will comment one out and use the other for testing this scenario.
ArtistInfoResponse IMusicRepository.GetArtistResponse(string artistName)
{
var client = new RestClient($"https://api.deezer.com/search?q=artist:{artistName}");
// returns this as url https://localhost:44343/Home/ArtistInformation?artistName=Dave%20Matthews%20Band
var client = new RestClient($"https://api.deezer.com/search?q=artist:\"Dave Matthews Band\"");
// returns this in url https://localhost:44343/Home/ArtistInformation?artistName=Dave%20Matthews%20Band
var request = new RestRequest(Method.GET);
var cancellationTokenSource = new CancellationTokenSource();
IRestResponse response = client.Execute(request);
if (response.IsSuccessful)
{
// Deserialize the string content into JToken object
var content = JsonConvert.DeserializeObject<JToken>(response.Content);
// Deserialize the JToken object into our ArtistInfoResponse Class
return content.ToObject<ArtistInfoResponse>();
}
return null;
}
