我架构的以lucene为技术的全文检索分为lucene检索模块，索引文件生成器和WEB检索测试三个部分组成
结构如下：
![image]( "image")
lucene模块它由通过检索项和几个具体检索业务子项目组成
通过功能项目结构为：
![image]( "image")
其中的一个子项目结构为
![image]( "image")
子项目只负责自己业务的实现，createIndexFile这个类型主要实现的是建立索引，而FieldKeys类型主要是设置表字段
在WEB层测试时可以通过这段代码进行调用
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();
}
而从索引文件反序列化的代码被我抽象到controller的基类中，如下
public class ControllerBase : Controller
{
/// <summary>
/// 调÷用?WIN API方?法¨
/// 非?托D管ü资ê源′
/// </summary>
/// <param name="section"></param>
/// <param name="key"></param>
/// <param name="def"></param>
/// <param name="retVal"></param>
/// <param name="size"></param>
/// <param name="filePath"></param>
/// <returns></returns>
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
/// <summary>
/// 得?到?索÷引y文?件t路·径?
/// </summary>
/// <param name="configPath"></param>
/// <returns></returns>
protected string GetIndexPath(string configPath)
{
StringBuilder sbPath = new StringBuilder(500);
GetPrivateProfileString("Index", "Path", "", sbPath, 500, configPath);
return sbPath.ToString();
}
/// <summary>
/// 从ó索÷引y文?件t中D重?到?数y据Y，?根ù据Y关?键ü字?
/// </summary>
/// <param name="keyword"></param>
/// <returns></returns>
protected virtual SearchResult GetDataFromIndex(QueryTerm queryTerm)
{
QueryTerm term = new QueryTerm();
term.KeyWord = queryTerm.KeyWord;
term.PageIndex = queryTerm.PageSize;
term.CategoryName = queryTerm.CategoryName;
term.PageSize = 10;
Search searcher = new Search(this.GetIndexPath(ConfigurationManager.AppSettings["Res_Item_IndexDocumentsPath"]), term);
return searcher.GetSearchResult();
}
}
}
