[Mohit-Chakraborty]

Library name and version

Azure.Search.Documents

Describe the bug

When a user sets the SessionId in SearchOptions for a query, the service does not receive the property.

Expected behavior

We expect to see SessionId passed to the service.

Actual behavior

Service-side logs show that SessionId was not passed.

Reproduction Steps

      private static void RunQueries(SearchClient srchclient)
      {
          SearchOptions options;
          SearchResults<Hotel> response;

          Console.WriteLine("Query #1: Search on empty term '*' to return all documents, showing a subset of fields...\n");

          options = new SearchOptions()
          {
              IncludeTotalCount = true,  
              SessionId = "123",
          };

          options.Select.Add("HotelId");
          options.Select.Add("HotelName");
          options.Select.Add("Rating");

          while (true)
          {
              response = srchclient.Search<Hotel>("*", options);
              WriteDocuments(response);
          }
      }
