3.多条件查询，实战中主要用这个

import org.elasticsearch.action.search.SearchRequestBuilder;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.index.query.*;
import org.elasticsearch.search.SearchHit;
import org.elasticsearch.search.SearchHits;
import org.junit.Test;/*** 多条件查询，实战中，主要是使用这个* @author XXL* @create 2019-08-11 14:11*/
public class MutilSearchDemo extends ClientDemo{/*** 模糊查找标题含有 “战”的,内容中必须没有“星球”的**/@Testpublic void searchMutil1(){SearchRequestBuilder srb = client.prepareSearch("firm").setTypes("dongzuo");QueryBuilder qb1 = QueryBuilders.matchPhraseQuery("title", "战");QueryBuilder qb2 = QueryBuilders.matchQuery("content","星球");SearchResponse response = srb.setQuery(QueryBuilders.boolQuery().must(qb1).mustNot(qb2)).execute().actionGet();SearchHits hits = response.getHits();for(SearchHit hit : hits){System.out.println(hit.getSourceAsString());}}/*** should 的使用 ， 提高得分* 标题含有战的* 得分：1.含有星球的得分 2. 出版日期在指定区间范围的得分*/@Testpublic void shouldSearch(){SearchRequestBuilder srb = client.prepareSearch("firm").setTypes("dongzuo");MatchPhraseQueryBuilder mqb = QueryBuilders.matchPhraseQuery("title", "战");MatchPhraseQueryBuilder mqb2 = QueryBuilders.matchPhraseQuery("content", "星球");RangeQueryBuilder range = QueryBuilders.rangeQuery("publishDate").gt("2018-01-01");SearchResponse response = srb.setQuery(QueryBuilders.boolQuery().must(mqb).should(mqb2).should(range)).execute().actionGet();SearchHits hits = response.getHits();for(SearchHit hit:hits){System.out.println(hit.getScore() + ":" +hit.getSourceAsString());}}/*** 标题含有战的* 过滤: 票价必须小于40的**/@Testpublic void filterSearch(){SearchRequestBuilder srb = client.prepareSearch("firm").setTypes("dongzuo");MatchPhraseQueryBuilder q1 = QueryBuilders.matchPhraseQuery("title", "战");RangeQueryBuilder priceRange = QueryBuilders.rangeQuery("price").lt(40);SearchResponse response = srb.setQuery(QueryBuilders.boolQuery().must(q1).filter(priceRange)).execute().actionGet();SearchHits hits = response.getHits();for(SearchHit hit: hits){System.out.println(hit.getSourceAsString());}}
