solr json ajax

用ajax去请求solr服务。返回json�Q�然后解释。让solr�q�回json的参数是wt=json。然后javascript用evel()解释成对象�?br /> 我的solr会返回：auother,title,introduce�q�几个域。先创徏一个jsp或html�Q�如�Q�json.jsp

1.json.jsp关键的html内容

  <form action="select/" name="f1" method="get" onsubmit="xmlhttpPost('/solr/select'); return false;" >
      Chenlb:
      <input type="text" name="q" size="80" value="文档">
      <input name="start" type="hidden" value="0">
    <input name="rows" type="hidden" value="10">
    <input name="indent" type="hidden" value="on">
    <input name="wt" type="hidden" value="">
      <input type="button" value=" �?nbsp;�?nbsp;" onclick="xmlhttpPost('/solr/select');">
      <input type="button" value=" get json " onclick="document.forms['f1'].wt.value='json';document.forms['f1'].submit();">
      <input type="button" value=" get xml " onclick="document.forms['f1'].wt.value='';document.forms['f1'].submit();">
  form>
  <div style="background-color: #ccccff; height: 15px;">div>
  <p>
    <div id="header">div>
    <div id="response">div>
    <table id="docs" class="tab" cellspacing="1">
        <tr height="25" style="background-color: #cccccc; color: #0000ff;">
            <td>作�?/span>td>
            <td>��?/span>td>
            <td>标题td>
            <td>scoretd>
        tr>
    table>

2.javascript部分

3.现在可以搜烦了�?br /> http://localhost:8080/solr/json.jsp

最�q�看下Lucene的东西，把它写下来可以看下。Lucene�l�构和工作原理我��׃��说了�Q�网上好多�?br />
