我心中的核心组件（可插拔的AOP）~第十四回 全文检索架构~终于设计了一个自己满意的Lucene架构

public class HomeController : ControllerBase
   {
       Web.Helper.UIHelper ui;

       public ActionResult Index(string keyword, string categoryName, int? page)
       {
           string _keyword = (keyword ?? string.Empty).Trim();
           System.Collections.Specialized.NameValueCollection nv = new System.Collections.Specialized.NameValueCollection();
           nv.Add("keyword", _keyword);
           ui = new Web.Helper.UIHelper(Request.Url.ToString(), nv);
           ViewData["Message"] = "欢?迎-使1用? ASP.NET MVC!";
           SearchResult result = GetDataFromIndex(new QueryTerm { KeyWord = _keyword, CategoryName = categoryName, PageSize = 1 });
           ViewData["result"] = result;
           ViewData["page"] = ui.GetPage(page ?? 1, 10, result.Total);
           return View();
       }
