html文件利用ajax方法通过servlet文件访问数据库获取提示。汉字无法匹配？0

Access数据库Goods表：

html文件suggest.html：
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<script language="JavaScript" type="text/javascript" src="ajax_search.js"></script>
<style type="text/css" media="screen">

<h3>实现搜索提示</h3>
<div style="width: 500px;">
<input type="text" id="txtSearch" name="txtSearch" onKeyUp="searchSuggest();" autocomplete="off" />
<input type="submit" id="cmdSearch" name="cmdSearch" value="搜索"/><br />
<div id="search_suggest"></div>
</div>
</center>
</body>
</html>

ajax_search.js：
var searchReq = createAjaxObj();
function createAjaxObj()
{
   var httprequest=false;
   if (window.XMLHttpRequest)           //为非IE浏览器生成XmlHttpRequest对象
{
       httprequest=new XMLHttpRequest()
       if (httprequest.overrideMimeType)      httprequest.overrideMimeType('text/xml')
   }
   else if (window.ActiveXObject)      //为IE浏览器生成XmlHttpRequest对象
   {
        try
        {
               httprequest=new ActiveXObject("Msxml2.XMLHTTP");
        }
        catch (e)

        }
    }
    return httprequest
}
function searchSuggest()
{
if (searchReq.readyState == 4 || searchReq.readyState == 0)
               {
var str = escape(document.getElementById('txtSearch').value);
searchReq.open("GET", 'search?search=' + str, true);//向服务器端发送请求
searchReq.onreadystatechange = handleSearchSuggest; //设置回调函数
searchReq.send(null);
}
}
function handleSearchSuggest()
{ //这是回调函数，处理从服务器端返回的信息
if (searchReq.readyState == 4)
                {
var ss = document.getElementById('search_suggest')
ss.innerHTML = '';
var str = searchReq.responseText.split("\n");
for(i=0; i < str.length - 1; i++)
                               {
var suggest = '<div onmouseover="javascript:suggestOver(this);" ';
suggest += 'onmouseout="javascript:suggestOut(this);" ';
suggest += 'onclick="javascript:setSearch(this.innerHTML);" ';
suggest += 'class="suggest_link">' + str[i] + '</div>';
ss.innerHTML += suggest;
ss.style.display="block";
}
}
}
function suggestOver(div_value)
{
div_value.className = 'suggest_link_over';
}
function suggestOut(div_value)
{
div_value.className = 'suggest_link';
}
function setSearch(value)
{
document.getElementById('txtSearch').value = value;
document.getElementById('search_suggest').innerHTML = '';
document.getElementById('search_suggest').style.display="none";
}

servlet文件SearchSuggest.java：
package com;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SearchSuggest extends HttpServlet
{
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, java.io.IOException
{
                                response.setCharacterEncoding("UTF-8");
String search = request.getParameter("search"); //接受参数值

String sql = "select GoodsName from Goods where GoodsName like '"+search+"%' order by GoodsName";//设置查询语句
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
ArrayList vData = new ArrayList();
java.io.PrintWriter out = response.getWriter();
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //注册数据库连接驱动

String MdbPath = "F:/sneaker/Tomcat/webapps/search/database/#costume.mdb";
String url= "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=" + MdbPath ;
conn = DriverManager.getConnection(url);

stmt = conn.createStatement();
rs = stmt.executeQuery(sql); //执行查询
while (rs.next())
{
vData.add(rs.getString("GoodsName"));
}
StringBuilder buf = new StringBuilder();
for (int i=0;i<vData.size();i++)
{
String keyword = (String)vData.get(i);
buf.append(keyword+"\n");
}
out.print(buf.toString());//向客户端输出信息
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (stmt != null)
stmt.close();
if (conn != null)
conn.close();
} catch (SQLException sqle) {
}
}
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException
{
doPost(request, response);
}
}

效果当输入为空时，可以调出数据表中所有信息汉字及数字正常显示：

当输入数字7时，可以匹配：

当输入汉字儿童或额时，匹配信息没有显示，是因为所输入的汉字编码有误吗，没有传递或传递后编码不匹配吗？求解？

js方法：function searchSuggest()需要进行改造。
searchReq.open("GET", 'search?search=' + str, true);//向服务器端发送请求
searchReq.onreadystatechange = handleSearchSuggest; //设置回调函数
searchReq.send(null);
上面三行代码改为如下：
searchReq.open("GET", 'search', true);//向服务器端发送请求
searchReq.onreadystatechange = handleSearchSuggest; //设置回调函数
searchReq.send("search=" + str);
