多字符串是最简单的一种,例如,搜索标题是 War and Peace ,作者是Leo Tolstoy ,直接用bool连接两个match查询即可.(这里面War and Peace和Leo Tolstoy就是多字符串,title和author是多字段) GET /_search { "query": { "bool": { "should": [ { "match": { "title": "War and Peace" }}, { "matc...
在es中,multi_match就是针对单字符串多字段查询的解决方案,包括三种查询:best_fields,most_fields,cross_fields。 一,best_fields 多字段查询中,单字段匹配度最高的那个文档的算分最高。 插入测试数据: PUT multi_query_index/_bulk {"index":{"_id":1}} {"title":"my bark dogs","body":"cats and do...
③matchPhraseQuery对中文精确匹配 queryBuilder.matchPhraseQuery("key", value) ④matchQuery("key", Obj) 关键字模糊+分词匹配 queryBuilder.matchQuery(key, value); ⑤multiMatchQuery("text", "field1", "field2"..); 匹配多个字段, 关键字模糊+分词匹配 queryBuilder.multiMatchQuery(value, key1, key...
这是查询语句, spring data es生成的 { "query": { "bool": { "must": [ { "nested": { "query": { "multi_match": { "query": "星火通讯", "fields": [ "nameValues.entityName^1.0", "nameValues.firstName^1.0", "nameValues.originalScriptNames^1.0", "nameValues.singleStringNames^1.0"...
5. multi-match 要求搜索三个字段,其中一个字段权重乘2,最终得分为每个字段得分相加(也就是设置 type 为 most_fields)。 6. cross-cluster search 跨集群搜索 题目明确告诉你不需要配置 remote cluster,环境已经配好了,只要写一个跨集群的 query 就行了,query 的内容也很简单,里面会有一个 sort 排序。

8、匹配短语检索( Match Phrase Query) public Response<List<Book>> phrase(String query) {MultiMatchQueryBuilder queryBuilder = new MultiMatchQueryBuilder(query).field(Constants.TITLE).field(Constants.SUMMARY).type(MultiMatchQueryBuilder.Type.PHRASE).slop(3);SearchRequestBuilder requestBuilder = client....
后面是要匹配的字段.withQuery(QueryBuilders.multiMatchQuery(cont,"remark","remark2","remark3"))// 也就是短语查询,中间不能打断,比如说查询 love you 这个短句,在remark中就不能被打断叉开).withQuery(QueryBuilders.matchPhraseQuery("remark","love you"));es_personRepository.search(nativeSearchQuery...
