今天小编就为大家分享一篇关于elasticsearch kibana简单查询讲解,小编觉得内容挺不错的,现在分享给大家,具有很好的参考价值,需要的朋友一起跟随小编来看看吧
一、简单的crud操作
1、添加
put /index/type/id
{
 "json数据"
}
2、查询
get /index/type/id
3、修改
post /index/type/id/_update
{
 "doc": {
  "field": "值"
 }
}
4、删除
delete /index/type/id
二、搜索
搜索可以分成六大类

  • 1、query string search
  • 2、query dsl
  • 3、query filter
  • 4、full-text search
  • 5、phrase search
  • 6、highlight search
1、query string search
搜索全部:get supplier/user/_search
{
 "took": 2,
 "timed_out": false,
 "_shards": {
  "total": 5,
  "successful": 5,
  "failed": 0
 },
 "hits": {
  "total": 3,
  "max_score": 1,
  "hits": [
   {
  "_index": "supplier",
  "_type": "user",
  "_id": "2",
  "_score": 1,
  "_source": {
   "name": "lisi",
   "age": 26,
   "address": "bei jing tong zhou",
   "price": 10000,
   "dept": [
    "kaifabu"
   ]
  }
   },
   {
  "_index": "supplier",
  "_type": "user",
  "_id": "1",
  "_score": 1,
  "_source": {
   "name": "zhangsan",
   "age": 30,
   "address": "bei jing chang chun jie",
   "price": 15000,
   "dept": [
    "kaifabu",
    "yanfabu"
   ]
  }
   },
   {
  "_index": "supplier",
  "_type": "user",
  "_id": "3",
  "_score": 1,
  "_source": {
   "name": "wangwu",
   "age": 26,
   "address": "bei jing tong zhou yun he ming zhu",
   "price": 13000,
   "dept": [
    "kaifabu"
   ]
  }
   }
  ]
 }
}
took:耗费了几毫秒
timed_out:是否超时,这里是没有
_shards:数据拆成了5个分片,所以对于搜索请求,会打到所有的primary shard(或者是它的某个replica shard也可以)
hits.total:查询结果的数量,3个document
hits.max_score:score的含义,就是document对于一个search的相关度的匹配分数,越相关,就越匹配,分数也高
hits.hits:包含了匹配搜索的document的详细数据
2、query dsl
查询所有
get supplier/user/_search
{
 "query": { "match_all": {} }
}
查询全部并且排序
get suppluer/user/_search
{
 "query": {
  "match_all": {}
 }
 , "sort": [
  {
   "price": {
  "order": "desc"
   }
  }
 ]
}
分页查询
get supplier/user/_search
{
 "query": { "match_all": {} },
 "from": 1,
 "size": 1
}
指定要查询显示的field
get supplier/user/_search
{
 "query": { "match_all": {} },
 "_source": ["name", "price"]
}
3、query filter
搜索name为‘lisi'并且price大于1500的
get supplier/user/_search
{
  "query" : {
  "bool" : {
    "must" : {
    "match" : {
      "name" : "lisi"
    }
    },
    "filter" : {
    "range" : {
      "price" : { "gt" : 1500} 
    }
    }
  }
  }
}
4、full-text search(全文检索)
address这个字段,会先被拆解,建立倒排索引
get /ecommerce/product/_search
{
  "query" : {
  "match" : {
    "address" : "bei jing"
  }
  }
}
5、phrase search(短语搜索)
跟全文检索相对应,相反,全文检索会将输入的搜索串拆解开来,去倒排索引里面去一一匹配,只要能匹配上任意一个拆解后的单词,就可以作为结果返回
phrase search,要求输入的搜索串,必须在指定的字段文本中,完全包含一模一样的,才可以算匹配,才能作为结果返回
get /ecommerce/product/_search
{
  "query" : {
  "match_phrase" : {
    "address" : "bei jing"
  }
  }
}
6、highlight search(高亮搜索结果)
get /ecommerce/product/_search
{
  "query" : {
  "match" : {
    "address" : "bei jing"
  }
  },
  "highlight": {
  "fields" : {
    "address" : {}
  }
  }
}
