让.Text的搜索引擎支持二级域名

最近在做.Text Blog的Wap版，因为手机上输入比电脑上更难，所以，如果用户手动输入地址访问Blog的话，会对没有意义又繁长的URL非常反感，所以，花了点时间做了.Text对二级域名的支持并对其地址分析功能做了些优化，可是做好后发现，.Text的搜索引擎并不支持这种域名方式，没办法，只好对它的搜索引索又动了点小手术。(博客园现在有点慢啊)

1、对Web.config的修改：

<SearchConfiguration type="Dottext.Search.SearchConfiguration, Dottext.Search" urlFormat="http://{1}{0}/Blog/{2}/{3}.aspx"
virtualPath="~/SearchIndex" physicalPath="D:\Code\MSS1\Blog\DotTextWeb\SearchIndex" domains=".tzl.com"
pageSize="20" />

2、将Dottext.Search.EntryData类的CreateDoc(IDataReader reader)方法改成这样

private Document CreateDoc(IDataReader reader)
{
//Null values are not allowed in the index

Document doc = new Document();
try
{
doc.Add(Field.Text(SearchConfiguration.Author,(string)reader["Author"]));
doc.Add(Field.Text(SearchConfiguration.Title,(string)reader["Title"]));
string body = (string)reader["Text"];
doc.Add(Field.UnIndexed(SearchConfiguration.Body,body));
doc.Add(Field.Text(SearchConfiguration.Link,string.Join(" ",GetLinks(body))));
doc.Add(Field.Text(SearchConfiguration.RawPost,regexStripHTML.Replace(body,string.Empty)));
DateTime dateCreated = (DateTime)reader["DateAdded"];
doc.Add(Field.UnIndexed(SearchConfiguration.DateCreated,dateCreated.ToLongDateString()));
string app = (string)reader["Application"];
doc.Add(Field.Text(SearchConfiguration.Blog,app));
//Do we really need this?
//doc.Add(Field.Text(SearchConfiguration.Description,reader["Description"].ToString()));

string host = (string)reader["Host"];
doc.Add(Field.Text(SearchConfiguration.Domain,host));
int posttype = (int)reader["PostType"];
doc.Add(Field.UnIndexed(SearchConfiguration.PostType,posttype.ToString()));
string permaLink  = null;
SearchConfiguration searchConfig = SearchConfiguration.Instance();
if((PostType)posttype == PostType.BlogPost)
{
//permaLink = string.Format(SearchConfiguration.Instance().UrlFormat,host,app, "archive/" + dateCreated.ToString("yyyy'/'MM'/'dd"),reader["EntryID"]);
                    permaLink = string.Format(searchConfig.UrlFormat,searchConfig.Domains,app, "archive/" + dateCreated.ToString("yyyy'/'MM'/'dd"),reader["EntryID"]);
}
else if((PostType)posttype == PostType.Comment)
{
permaLink =    reader["SourceUrl"].ToString()+"#"+reader["EntryID"].ToString();
}
else
{
//permaLink = string.Format(SearchConfiguration.Instance().UrlFormat,host,app, "articles",reader["EntryID"]);
                    permaLink = string.Format(searchConfig.UrlFormat,searchConfig.Domains,app, "articles",reader["EntryID"]);
}
int feedbackCount = (int)reader["FeedbackCount"];
int webviewCount = (int)reader["WebViewCount"];
int boost = weighter.Calculate(body.Length,feedbackCount,webviewCount,dateCreated,(PostType)posttype);
doc.SetBoost(boost);
doc.Add(Field.UnIndexed(SearchConfiguration.BoostFactor,boost.ToString()));
doc.Add(Field.UnIndexed(SearchConfiguration.PermaLink,permaLink));
}
catch(Exception e)
{
Dottext.Framework.Logger.LogManager.Log("CreateDoc Fail","EntryID is "+reader["EntryID"]);
}
return doc;
}
