ik 分词器和ElasticSearch查询条件

title：百度张亚勤：ABC时代来了，迎战云计算“马拉松”
创建mapping的时候指定了title字段的分词器为ik，分词结果为
{"tokens": [

通过张亚勤或者云计算搜不到内容
查询语句为
{
  "query": {
    "term": {
      "title": "张亚勤"
    }
  }
}
java代码为

response = client.prepareSearch("blog") .setTypes("article") .setQuery(QueryBuilders.termQuery("title", "张亚勤")) .setFrom(0).setSize(60).setExplain(true) .execute() .actionGet();
问题：ik分词分出来的大部分是两个汉字的，三个汉字就匹配不到了，怎么修改ik的配置，或者改一下查询条件，能够搜到相应的结果？
