1 搜索所有文档中还有某个字段的方法： localhost:9200/get-together/group/_search?pretty
{ "query": { "query_string": { "query": "elasticsearch" } } }
结果为
{ "took": 2, "timed_out": false, "_shards": { "total": 2, "successful": 2, "failed": 0 }, "hits": { "total": 2, "max_score": 1.3782532, "hits": [ { "_index": "get-together", "_type": "group", "_id": "3", "_score": 1.3782532, "_source": { "name": "Elasticsearch San Francisco", "organizer": "Mik", "description": "Elasticsearch group for ES users of all knowledge levels", "created_on": "2012-08-07", "tags": [ "elasticsearch" , "big data" , "lucene" , "open source" ], "members": [ "Lee" , "Igor" ], "location_group": "San Francisco, California, USA" } } , { "_index": "get-together", "_type": "group", "_id": "2", "_score": 0.10344465, "_source": { "name": "Elasticsearch Denver", "organizer": "Lee", "description": "Get together to learn more about using Elasticsearch, the applications and neat things you can do with ES!", "created_on": "2013-03-15", "tags": [ "denver" , "elasticsearch" , "big data" , "lucene" , "solr" ], "members": [ "Lee" , "Mike" ], "location_group": "Denver, Colorado, USA" } } ] } }
只要某个文档中还有该字段都会被查出，也可以设置 " default_field ": " name "，"default_operator": "AND"，and表示只有当某文档中出现搜索的完整字段才会匹配，例如 localhost:9200/get-together/group/_search?pretty
{ "query": { "query_string": { "query": "elasticsearch san francisco", "default_field": "name", "default_operator": "AND" } } }
也可以设置为"default_operator": "OR",就是当出现elasticsearche san francisco某一个字段都会匹配被查出，另外一种可以实现该结果的查询是： "query": "name:elasticsearch AND name:san AND name:francisco"
