elk之查询（单个或多个）type所有数据，条件查询，分页查询，排序

java连接es：

1、接口：

    /**
     * 查询（单个或多个）type所有数据，条件查询，分页查询，排序
     * @param client
     * @param indexName
     * @param typeName
     */
    public void searchAllStudent(TransportClient client, String indexName, String typeName);

2.实现类：（注释！！）

@Override
    public void searchAllStudent(TransportClient client, String indexName, String typeName) {

//        多索引,多type查询
//        SearchResponse searchResponse = client.prepareSearch("shb01","shb02").setTypes("stu","tea")

        //创建SearchResponse对象
        SearchResponse searchResponse = client.prepareSearch(indexName)
                .setTypes(typeName)
                //查询所有
                .setQuery(QueryBuilders.matchAllQuery())
                .setSearchType(SearchType.QUERY_THEN_FETCH)
                //根据夏文杰查询name，数据库like,指定查询条件,这里不支持通配符 * ？
                .setQuery(QueryBuilders.matchQuery("name", "夏文杰"))
                //等价于SQL语句，支持一个值同时匹配多个字段,就是，where name=2 or age=2
                .setQuery(QueryBuilders.multiMatchQuery("2", "name", "age"))
                //根据条件查询,支持通配符大于等于0小于等于19
                .setQuery(QueryBuilders.queryStringQuery("name:夏文杰 AND age:[0 TO 19]"))
                //查询时不分词
                .setQuery(QueryBuilders.termQuery("name", "夏文杰4"))
                //分页
                .setFrom(0).setSize(10)
                //排序
                .addSort("age", SortOrder.DESC)
                .setExplain(true)//按照查询数据的匹配度返回数据
                .get();
        SearchHits hits = searchResponse.getHits();
        long total = hits.getTotalHits();
        System.out.println(total);
        //获取满足条件数据的详细内容
        SearchHit[] searchHits = hits.hits();
        for (SearchHit s : searchHits) {
            System.out.println(s.getSourceAsString());
        }
    }

3.测试类：

  searchService.searchAllStudent(ConEsUtil.creatConEs(),"school1","student");
