must :  相当于 MySQL and  should ： 相当于MySQL or (效率低)

setExplain(true)  匹配顺序

 

BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();  
        boolQueryBuilder.must(QueryBuilders.wildcardQuery("name", "*豆鼓焗带鱼*")).must(termQuery("foodType", "套餐"));
SearchResponse response1 = EsUtils.getClient()
.prepareSearch("food")
.setTypes("_doc")
.setQuery(boolQueryBuilder)
.setFrom(Integer.parseInt("0"))
.setSize(Integer.parseInt("10"))
.setExplain(true)    
                .execute()    
                .actionGet();
for(SearchHit hit:response1.getHits().getHits()){
System.out.println(hit.getSourceAsString());

}

 

《---------------------编辑----------------------》

                UpdateRequest updateRequest = new UpdateRequest();

updateRequest.index("food2");
updateRequest.type("_doc");
updateRequest.id("cAjpPmMBFth1dx0K4mIh");
updateRequest.doc(XContentFactory.jsonBuilder().startObject().field("name", "你好李四").endObject());

client.update(updateRequest).get();

《新建》

                Map<String, Object> json = new HashMap<String, Object>();
json.put("style","风格");
json.put("tag","tag");
json.put("taste","taste");
json.put("tech","tech");

        EsUtils.index("food", "_doc", json);

《删除》

            EsUtils.delete(indexName, type, id);
