但是这样的情况，站内搜索一般还需要操作数据库。如何不操作数据库而直接按关键词索引站内的页面？
实际上用一个asp文件即可实现此功能，以下是一个简单的例子，需要的时候可以根据网站风格做界面和功能调整。
经过测试，我发现对于网页数量较多的站点，代码执行速度比较慢，不如直接操作数据库效率高，但这个功能的实现，对于小型网站的站内搜索也许更为适合。代码如下：
<%
Head = "站内搜索"
SearchString = Request("SearchString")
count=0
'把当前目录的实际路径转换为虚拟路径
Function UnMapPath( Path )
UnMapPath = Replace(Mid(Path, Len(Server.MapPath("/")) + 1), "", "/")
End Function
Function SearchFile( f, s, title )
Set fo = fs.OpenTextFile(f)
content = fo.ReadAll
fo.Close
SearchFile = InStr(1, content, S, vbTextCompare) > 0
If SearchFile Then
pos1 = InStr(1, content, "<TITLE>", vbTextCompare)
pos2 = InStr(1, content, "</TITLE>", vbTextCompare)
title = ""
If pos1 > 0 And pos2 > 0 Then
title = Mid( content, pos1 + 7, pos2 - pos1 - 7 )
End If
End If
End Function
Function FileLink( f, title )
vPath = UnMapPath( f.Path )
If title = "" Then title = f.Name
FileLink = "<A HREF=""" & vPath & """>" & title & "</A>"
FileLink = "<UL>·" & FileLink & "</UL>"
End Function
Sub SearchFolder( fd, s )
found = False
For each f In fd.Files
pos = InStrRev(f.Path, "." )
If pos > 0 Then
ext = Mid(f.Path, pos + 1 )
Else
ext = ""
End If
If LCase(ext) = "htm" Then
If SearchFile( f, s, title ) Then
Response.Write FileLink(f, title)
count=count+1
' Response.Write cstr(count)
End If
End If
Next
For each sfd In fd.SubFolders
SearchFolder sfd, s
Next
End Sub
