Elasticsearch 之（50） Java API 对汽车品牌进行全文检索、精准查询和前缀搜索

其实就要用到我们之前《 Elasticsearch 之（21）前缀搜索、通配符搜索、正则搜索、推荐搜索 和 模糊搜索》中讲解的语法

package com.es.app;

        TransportClient client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

            System.out.println(searchHit.getSourceAsString());
        }

                .get();

        for(SearchHit searchHit : searchResponse.getHits().getHits()) {

        client.close();
