Search Results don't match

Content

Hello,

We currently use the API to search our KB. When pulling answers, the same results are not returned as when doing a search on the portal. We need these results to match. On another instance using the same code answers match exactly. Any idea what we could be doing wrong here? Is there some option we are not setting somewhere that could affect the order answers are returned in?

Code Snippet

             RightNowKF_Service.ContentSearchOrigin origin = new RightNowKF_Service.ContentSearchOrigin();
                origin.Name = "Search Normal";
                origin.ID = new RightNowKF_Service.ID() { id = 1, idSpecified = true };

                RightNowKF_Service.ServiceCategoryContentFilter[] contentFilters = new RightNowKF_Service.ServiceCategoryContentFilter[1];
