②. match、match_phrase、multi_math查询
- ①. match:如果是非字符串,会进行精确匹配
基本类型(非字符串),精确控制 GET bank/_search { "query": { "match": { "account_number": "20" } } } match返回account_number=20的数据 查询结果: { "took" : 1, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 1, // 得到一条 "relation" : "eq" }, "max_score" : 1.0, # 最大得分 "hits" : [ { "_index" : "bank", "_type" : "account", "_id" : "20", "_score" : 1.0, "_source" : { # 该条文档信息 "account_number" : 20, "balance" : 16418, "firstname" : "Elinor", "lastname" : "Ratliff", "age" : 36, "gender" : "M", "address" : "282 Kings Place", "employer" : "Scentric", "email" : "elinorratliff@scentric.com", "city" : "Ribera", "state" : "WA" } } ] } }
②. match:如果是字符串,会进行全文检索
字符串,全文检索 GET bank/_search { "query": { "match": { "address": "kings" } } } 全文检索,最终会按照评分进行排序,会对检索条件进行分词匹配 { "took" : 30, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 2, "relation" : "eq" }, "max_score" : 5.990829, "hits" : [ { "_index" : "bank", "_type" : "account", "_id" : "20", "_score" : 5.990829, "_source" : { "account_number" : 20, "balance" : 16418, "firstname" : "Elinor", "lastname" : "Ratliff", "age" : 36, "gender" : "M", "address" : "282 Kings Place", "employer" : "Scentric", "email" : "elinorratliff@scentric.com", "city" : "Ribera", "state" : "WA" } }, { "_index" : "bank", "_type" : "account", "_id" : "722", "_score" : 5.990829, "_source" : { "account_number" : 722, "balance" : 27256, "firstname" : "Roberts", "lastname" : "Beasley", "age" : 34, "gender" : "F", "address" : "305 Kings Hwy", "employer" : "Quintity", "email" : "robertsbeasley@quintity.com", "city" : "Hayden", "state" : "PA" } } ] } }
- ③. match_phrase(不拆分匹配):将需要匹配的值当成一整个单词(不分词)进行检索
- match_phrase:不拆分字符串进行检索
- 字段.keyword:必须全匹配上才检索成功(精确匹配)
前面的是包含mill或road就查出来,我们现在要都包含才查出 GET bank/_search { "query": { "match_phrase": { "address": "mill road" # 就是说不要匹配只有mill或只有road的,要匹配mill road一整个子串 } } } 查处address中包含mill road的所有记录,并给出相关性得分 { "took" : 32, "timed_out" : false, "_shards" : { "total" : 1, "successful" : 1, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : { "value" : 1, "relation" : "eq" }, "max_score" : 8.926605, "hits" : [ { "_index" : "bank", "_type" : "account", "_id" : "970", "_score" : 8.926605, "_source" : { "account_number" : 970, "balance" : 19648, "firstname" : "Forbes", "lastname" : "Wallace", "age" : 28, "gender" : "M", "address" : "990 Mill Road", # "mill road" "employer" : "Pheast", "email" : "forbeswallace@pheast.com", "city" : "Lopezo", "state" : "AK" } } ] } }
