我想使用jQuery从以下html代码中获取'P'标签的内容.

<div id="div_id_disciplina" class="form-group  ">
<label for="id_disciplina" class="control-label  ">
    Disciplina
</label>
<div class="">
    <ul class="token-input-list-facebook">
        <li class="token-input-token-facebook">
            <p>Áudio e Vídeo</p>
            <span class="token-input-delete-token-facebook">×</span>
        </li>
        <li class="token-input-input-token-facebook">
            <input type="text" autocomplete="off" id="token-input-id_disciplina">    
        </li>
    </ul>
    <textarea class="form-control" id="id_disciplina" name="disciplina"></textarea>
</div>

怎么实现呢？提前致谢.

在elasticsearch 5.6.2和5.6.3（Ubuntu 16.04）中，此查询

GET _search
{
   "simple_query_string": {
      "query": "test1 + test2",
      "analyzer": "snowball",
      "fields": ["myfield"],
      "default_operator": "and"
   }
}

导致此错误

{
   "error": {
      "root_cause": [
         {
            "type": "parsing_exception",
            "reason": "Unknown key for a START_OBJECT in [simple_query_string].",
            "line": 2,
            "col": 44
         }
      ],
      "type": "parsing_exception",
      "reason": "Unknown key for a START_OBJECT in [simple_query_string].",
      "line": 2,
      "col": 44
   },
   "status": 400
}

这与此处的第一个示例几乎相同https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html

有人能帮我吗？
