<%
Set conn = Server.CreateObject("ADODB.Connection")
conn.open strPath
dim rsResult
set rsResult = Server.Createobject("ADODB.recordset")

rsResult=search(strKeyword)
%>

Function Search(keyword) 'keywordÀïµÄ¹Ø¼ü×ÖÓÿոñ·Ö¿ª

Dim sqlQuest
Dim keywordGroup
dim rs
set rs= server.createobject("ADODB.Recordset")
keywordGroup = Split(keyword)

keyword = keywordGroup(i)
Else
keyword = keywordGroup(i) & "and" & keyword

Commodity LIKE " & keyword
rs.Open sqlQuest, conn
Dim a
Do While Not rs.EOF
