elasticsearch基本查询二（英文分词）term和terms查询

term和terms查询(查找zhaoliu这个人的信息)
term query会去倒排索弓|中寻找确切的term,它并不知道分词器的存在。这种查询适合keyword、numeric. date.
term:查询某个字段里含有某个关键词的文档
GET /lib3/user/_search/ { "query":{ "term": {interests": "changge"}}}
terms:查询某个字段里合有多个关键词的文档
GET /ib3/user/_search { "query":{ "terms':{ "interests": ["hejiu","changge']}}

GET /lib3/user/_search
{"query": {"term": {"name": {"value": "zhaoliu"}}}
}GET /lib3/user/_search
{"query": {"term": {"name": "zhaoliu"}}
}
{"took" : 5,"timed_out" : false,"_shards" : {"total" : 5,"successful" : 5,"skipped" : 0,"failed" : 0},"hits" : {"total" : 1,"max_score" : 0.2876821,"hits" : [{"_index" : "lib3","_type" : "user","_id" : "1","_score" : 0.2876821,"_source" : {"name" : "zhaoliu","address" : "hei long jiang sheng tie ling shi","age" : 50,"birthday" : "1970-12-12","interests" : "xi buan hejiu, duanlian, lvyou"}}]}
}

查找兴趣爱好interests为hejiu changge的人的信息

GET /lib3/user/_search
{"query": {"terms": {"interests": ["hejiu","changge"]}}
}
{"took" : 56,"timed_out" : false,"_shards" : {"total" : 5,"successful" : 5,"skipped" : 0,"failed" : 0},"hits" : {"total" : 4,"max_score" : 1.0,"hits" : [{"_index" : "lib3","_type" : "user","_id" : "5","_score" : 1.0,"_source" : {"name" : "zhangsan","address" : "bei jing chao yang qu","age" : 29,"birthday" : "1988-10-12","interests" : "xi huan tingyinyue , changge , tiaowu"}},{"_index" : "lib3","_type" : "user","_id" : "2","_score" : 1.0,"_source" : {"name" : "zhaoming","address" : "bei jing hai dian qu qing he zhen","age" : 20,"birthday" : "1998-10-12","interests" : "xi huan hejiu, duanlian, changge"}},{"_index" : "lib3","_type" : "user","_id" : "1","_score" : 1.0,"_source" : {"name" : "zhaoliu","address" : "hei long jiang sheng tie ling shi","age" : 50,"birthday" : "1970-12-12","interests" : "xi buan hejiu, duanlian, lvyou"}},{"_index" : "lib3","_type" : "user","_id" : "3","_score" : 1.0,"_source" : {"name" : "lisi","address" : "bei jing hai dian qu qing he zhen","age" : 23,"birthday" : "1998-10-12","interests" : "xi huan hejiu,duanlian, changge"}}]}
}

只要含有一个关键词的都会被查询出来总共四个人有关于hejiu changge要么changge要么hejiu 要么两者都

如果我只想取前2个人使用from:0 (表示从第一个文档开始) size:2（取2个文档）

GET /lib3/user/_search
{"from":0,"size":2,"query": {"terms": {"interests": ["hejiu","changge"]}}
}
{"took" : 81,"timed_out" : false,"_shards" : {"total" : 5,"successful" : 5,"skipped" : 0,"failed" : 0},"hits" : {"total" : 4,"max_score" : 1.0,"hits" : [{"_index" : "lib3","_type" : "user","_id" : "5","_score" : 1.0,"_source" : {"name" : "zhangsan","address" : "bei jing chao yang qu","age" : 29,"birthday" : "1988-10-12","interests" : "xi huan tingyinyue , changge , tiaowu"}},{"_index" : "lib3","_type" : "user","_id" : "2","_score" : 1.0,"_source" : {"name" : "zhaoming","address" : "bei jing hai dian qu qing he zhen","age" : 20,"birthday" : "1998-10-12","interests" : "xi huan hejiu, duanlian, changge"}}]}
}

以上查询都是没有版本号的我们要获取版本号，只需要加一个version:true

GET /lib3/user/_search
{"version": true, "query": {"terms": {"interests": ["hejiu","changge"]}}
}
{"took" : 33,"timed_out" : false,"_shards" : {"total" : 5,"successful" : 5,"skipped" : 0,"failed" : 0},"hits" : {"total" : 4,"max_score" : 1.0,"hits" : [{"_index" : "lib3","_type" : "user","_id" : "5","_version" : 1,"_score" : 1.0,"_source" : {"name" : "zhangsan","address" : "bei jing chao yang qu","age" : 29,"birthday" : "1988-10-12","interests" : "xi huan tingyinyue , changge , tiaowu"}},{"_index" : "lib3","_type" : "user","_id" : "2","_version" : 1,"_score" : 1.0,"_source" : {"name" : "zhaoming","address" : "bei jing hai dian qu qing he zhen","age" : 20,"birthday" : "1998-10-12","interests" : "xi huan hejiu, duanlian, changge"}},{"_index" : "lib3","_type" : "user","_id" : "1","_version" : 1,"_score" : 1.0,"_source" : {"name" : "zhaoliu","address" : "hei long jiang sheng tie ling shi","age" : 50,"birthday" : "1970-12-12","interests" : "xi buan hejiu, duanlian, lvyou"}},{"_index" : "lib3","_type" : "user","_id" : "3","_version" : 1,"_score" : 1.0,"_source" : {"name" : "lisi","address" : "bei jing hai dian qu qing he zhen","age" : 23,"birthday" : "1998-10-12","interests" : "xi huan hejiu,duanlian, changge"}}]}
}
