88_熟练掌握ES Java API_对汽车品牌进行全文检索、精准查询和前缀搜索

添加数据

PUT /car_shop/cars/5
{
        "brand": "华晨宝马",
        "name": "宝马318",
        "price": 270000,
        "produce_date": "2017-01-20"
}

全文检索方法

SearchResponse response = client.prepareSearch("car_shop")
        .setTypes("cars")
        .setQuery(QueryBuilders.matchQuery("brand", "宝马"))                
        .get();

多字段搜索multiMatch

SearchResponse response = client.prepareSearch("car_shop")
        .setTypes("cars")
        .setQuery(QueryBuilders.multiMatchQuery("宝马", "brand", "name"))                
        .get();

termquery 方法

SearchResponse response = client.prepareSearch("car_shop")
        .setTypes("cars")
        .setQuery(QueryBuilders.commonTermsQuery("name", "宝马320"))                
        .get();

前缀搜索api

SearchResponse response = client.prepareSearch("car_shop")
        .setTypes("cars")
        .setQuery(QueryBuilders.prefixQuery("name", "宝"))                
        .get();

整体源码如下

                .build();
        
        TransportClient client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));  
    
        SearchResponse searchResponse = client.prepareSearch("car_shop")
                .setTypes("cars")
                .setQuery(QueryBuilders.matchQuery("brand", "宝马"))
                .get();
        
        for(SearchHit searchHit : searchResponse.getHits().getHits()) {
            System.out.println(searchHit.getSourceAsString());  
        }
        
        System.out.println("====================================================");
        
        searchResponse = client.prepareSearch("car_shop")

                .setQuery(QueryBuilders.multiMatchQuery("宝马", "brand", "name"))  
                .get();
        
        for(SearchHit searchHit : searchResponse.getHits().getHits()) {

        client.close();
