1、创建测试索引
PUT /test_index
{
"mappings": {
"test_type":{
"properties": {
"code":{
"type": "keyword"
},
"name":{
"type": "text",
"analyzer": "ik"
},
"count":{
"type": "integer"
}
}
}
},
"settings": {
"number_of_shards": 5,
"number_of_replicas": 1,
"max_result_window":10000,
"analysis": {
"analyzer": {
"ik":{
"tokenizer":"ik_max_word",
"stopwords":["的","是"]
}
}
}
}
}
2、插入数据
PUT test_index/test_type/1 #4代表索引记录的唯一标识,类似数据库表中主键
{
"code":"001",
"name":"万科企业股份有限公司"
}
PUT test_index/test_type/2
{
"code":"002",
"name":"万达集团股份有限公司"
}
PUT test_index/test_type/3
{
"code":"003",
"name":"阿里巴巴(中国)有限公司"
}
PUT test_index/test_type/4
{
"code":"004",
"name":"中国平安"
}
3、删除数据
DELETE test_index/test_type/4 #4代表索引记录的唯一标识,类似数据库表中主键
4、更新数据
回复删除的4数据
PUT test_index/test_type/4
{
"code":"004",
"name":"中国平安"
}
①覆盖更新
PUT test_index/test_type/4
{
"name":"中国平安"
}
②更新字段值
POST test_index/test_type/4/_update
{
"doc": {
"name":"中国平安保险(集团)股份有限公司"
}
}
5、查询数据
在kibana中默认只显示10条记录
①查询所有
方式1:
GET test_index/test_type/_search
方式2:
GET test_index/test_type/_search
{
"query":{
"match_all": {}
}
}
②根据指定分词字段查询
name:为索引中的中文分词字段
GET test_index/test_type/_search
{
"query":{
"match": {
"name": "中国"
}
}
}
③、根据指定不分词字段查询
GET test_index/test_type/_search
{
"query":{
"term": {
"code": "004"
}
}
}
④、根据文档id查询
查询描述:pXrY0GsBN9ZpEwHZ14it:文档id
方式1:GET 索引/类型/文档id
GET test_index/test_type/4
方式2:_id文档唯一的id
GET test_index/test_type/_search
{
"query":{
"match": {
"_id": "4"
}
}
}
⑤多条件查询
多条件and关系:
#逻辑:and关系 GET test_index/test_type/_search { "query": { "bool": { "must": [ {"match": { "question": "淘宝"}}, {"match": { "question": "软件"}} ] } } }
GET test_index/test_type/_search
{
"query":{
"bool": {
"must": [
{
"match": {
"name":"中国平安保险(集团)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
]
}
}
}
多条件or关系:
GET test_index/test_type/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"name":"中国平安保险(集团)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
]
}
}
}
多条件and和or关系混合使用:
GET test_index/test_type/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"name":"中国平安保险(集团)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
],
"must": [
{
"match": {
"count": 2
}
}
]
}
}
}
自定义排序:
GET test_index/test_type/_search
{
"query": {
"bool": {
"must" : [
{
"match" : {
"name" : {
"query" : "中国平安"
}
}
}
],
"adjust_pure_negative": true,
"boost": 1.0
}
},
"_source": {
"includes": ["code", "name"],
"excludes": []
},
"sort": [{
"count": {
"order": "desc"
}
}]
}
⑥指定查询条数
GET test_index/test_type/_search { "query": { "match": { "question": "淘宝" } }, "from": 1, #指定位移 "size": 5 #指定查询条数 }
⑦指定查询返回的字段
GET test_index/test_type/_search { "_source": ["question","nlp"], #返回字段数组 "query": { "match": { "question": "淘宝" } } }
⑧控制加载的字段
GET test_index/test_type/_search { "_source": {"includes": ["question","nlp"],"excludes": ["isSatisfied"]}, "query": { "match": { "question": "淘宝" } } }
⑨通配符
GET test_index/test_type/_search { "_source": {"includes": ["quest*"],"excludes": ["*Date"]}, "query": { "match": { "question": "淘宝" } } }
排序
GET test_index/test_type/_search { "sort": [ { "askTimes": { "order": "desc" } } ], "query": { "match_all": {} } }
前缀匹配
GET test_index/test_type/_search { "query": { "match_phrase_prefix": { "question": "万科" } } }
返回查询
GET test_index/test_type/_search { "query": { "range": { "askTimes": { "gte": 10, # "lte": 20 } } } }
wildcard查询
*代表0个或多个字符
?代表任意一个字符
GET test_index/test_type/_search { "query": { "wildcard": { "question": "万科*" } } }
模糊查询
GET test_index/test_type/_search { "query": { "fuzzy": {"question": "万科"} } }
高亮搜索结果
注:在Kibana中没有看到效果
GET test_index/test_type/_search { "query": { "match": { "question": "淘宝" } }, "highlight": { "fields": {"question":{}} } }
过滤查询
GET test_index/test_type/_search { "post_filter": { "term": { "askTimes": 10 } } }
过滤非空
GET test_index/test_type/_search { "query": { "bool": { "filter": { "exists": { "field": "nlp" } } } } }
聚合查询
sum,min,max,avg,cardinality:求基数,terms:分组
GET /test_index/test_type/_search { "size": 0, "aggs": { "askTimes_of_max": { #自定义名称 "max": { #最大值 "field": "askTimes" } } } }
符合查询:待整理
7、检查noop更新
默认情况下,不更改任何内容的更新会返回“result”:“noop”;
可以通过设置“detect_noop”来禁用此行为:false
PUT test_index/test_type/4
{
"code":"004",
"name":"中国平安保险(集团)股份有限公司",
"count":2,
"tags":["aa","bb"]
}
POST test_index/test_type/4/_update
{
"doc": {
"name":"中国平安保险(集团)股份有限公司"
},
"detect_noop":false
}
POST test_index/test_type/5
{
"script" : {
"source": "ctx._source.count += params.count",
"lang": "painless",
"params" : {
"count" : 4
}
},
"upsert" : {
"count" : 1
}
}
如果无论文档是否存在您都希望脚本运行,即脚本处理初始化文档而不是upsert元素,设置scripted_upsert为true:
POST test_index/test_type/5
{
"scripted_upsert":true,
"script" : {
"source": "ctx._source.count += params.count",
"lang": "painless",
"params" : {
"count" : 4
}
},
"upsert" : {
"count" : 1
}
}
同scripted_upsert,如果无论文档是否存在都希望脚本运行,即脚本处理初始化文档而不是upsert元素,设置doc_as_upsert为true(文档5不存在):
POST test_index/test_type/5/_update
{
"doc":{
"count":12
},
"doc_as_upsert":true,
"upsert":{
"count":16
}
}
查询结果:GET test_index/test_type/5
{
"_index": "test_index",
"_type": "test_type",
"_id": "5",
"_version": 11,
"found": true,
"_source": {
"count": 12
}
}
9、其他
①、统计索引文档数量
描述:GET 索引/类型/_count
GET test_index/test_type/_count
②检测分词效果
POST test_index/_analyze
{
"analyzer": "ik_max_word",
"text": "我是中国人"
}
