我是靠谱客的博主欢喜鞋子，最近开发中收集的这篇文章主要介绍如何做一个只搜索本网站的引擎？，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

searchfiles.html
<html>

<head>

<title>撼雪喷云之本网搜索引擎</title>

</head>

<body>

<tr>

<td align="center">请输入条目或关键词<input type="text" name="term" size="15"> <input type="submit" value="搜索"></td>

</tr>

</table>

</form>

</body></html>

searchfiles.asp
<%
SearchTerm = request.form("term")
Novalid=" a b c d e f g h i j k l m n o p q r s t u v w x y z yes no and more"
NovalidResponse ="你输入的内容过于简单,请返回重试!"

if instr(SearchTerm,Novalid)=0 then
Response. Write ("<CENTER><H2>搜索结果</H2></CENTER>")

FolderName= "FolderName"
ShowList()

else
Response.Write NovalidResponse
End if

SearchResponse=""
%>

<%
Sub ShowList()
FolderToCheck = server.mappath("\") &"/" & FolderName & "/"
Dim fs, f, f1, fc, s
Set fs = CreateObject("Scripting.FileSystemObject")
Set f = fs.GetFolder(FolderToCheck)
Set fc = f.Files
For Each f1 in fc

Wfile = f1.name
if right(Wfile, 5)=".html" OR right(Wfile, 4)=".htm" then
Wfile2 = FolderToCheck & Wfile
Set fs = CreateObject("Scripting.FileSystemObject")
Set a = fs.OpenTextFile(Wfile2)
ct = a.ReadAll
a.close
ct2=lcase(ct)
SearchTerm2 = lcase(SearchTerm)

if instr(ct2,SearchTerm2)>0 then

if instr(ct,"</title>")>0 then
longitud=instr(ct,"</title>")
longitud=longitud -1
ct=left(ct,longitud)
longitud2=len(ct)
longitud=instr(ct,"<title>")
longitud=longitud2 -longitud -6
ct=right(ct,longitud)
else
if instr(ct,"</title>")>0 then
longitud=instr(ct,"</title>")
longitud=longitud -1
ct=left(ct,longitud)
longitud2=len(ct)
longitud=instr(ct,"<title>")
longitud=longitud2 -longitud -6
ct=right(ct,longitud)
end if
end if

SearchResponse= SearchResponse +"<tr><td>"+ ct + "</td><td ALIGN=CENTER
VALIGN=MIDDLE>" + " <A HREF=" + "/" + FolderName + "/" + Wfile +"> More </A></td></tr>"
longitud=0
ct=""

end if
end if

Next

Response.Write ("<html><head><title>搜索结果</title></head><body BGCOLOR=FFFFFF><CENTER>")

Response.Write ("<TABLE BORDER=0 WIDTH=550><tr><td BGCOLOR=C0C0C0><FONT SIZE=5><B>搜索结果</B></FONT></td></tr></TABLE>")

Response.Write ("<TABLE BORDER=0 WIDTH=550>")
if SearchResponse<>"" then
Response.Write SearchResponse
else
Response.Write ("<tr><td>对不起,没有找到你输入的条目或关键词!</td></tr>")
end if
Response.Write ("</TABLE>")

Response.Write ("<TABLE BORDER=0 WIDTH=550><tr><td BGCOLOR=C0C0C0 ALIGN=RIGHT><FONT SIZE=1>现在调用专业搜索引擎<A HREF= http://www.yahoo.com.cn/ </A></FONT></td></tr></TABLE>")
