1、創建測試索引
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、插入數據
PUT test_index/test_type/1 #4代表索引記錄的唯一標識,類似數據庫表中主鍵
{
"code":"001",
"name":"萬科企業股份有限公司"
}
PUT test_index/test_type/2
{
"code":"002",
"name":"萬達集團股份有限公司"
}
PUT test_index/test_type/3
{
"code":"003",
"name":"阿里巴巴(中國)有限公司"
}
PUT test_index/test_type/4
{
"code":"004",
"name":"中國平安"
}
3、刪除數據
DELETE test_index/test_type/4 #4代表索引記錄的唯一標識,類似數據庫表中主鍵
4、更新數據
回復刪除的4數據
PUT test_index/test_type/4
{
"code":"004",
"name":"中國平安"
}
①覆蓋更新
PUT test_index/test_type/4
{
"name":"中國平安"
}
②更新字段值
POST test_index/test_type/4/_update
{
"doc": {
"name":"中國平安保險(集團)股份有限公司"
}
}
5、查詢數據
在kibana中默認只顯示10條記錄
①查詢所有
方式1:
GET test_index/test_type/_search
方式2:
GET test_index/test_type/_search
{
"query":{
"match_all": {}
}
}
②根據指定分詞字段查詢
name:為索引中的中文分詞字段
GET test_index/test_type/_search
{
"query":{
"match": {
"name": "中國"
}
}
}
③、根據指定不分詞字段查詢
GET test_index/test_type/_search
{
"query":{
"term": {
"code": "004"
}
}
}
④、根據文檔id查詢
查詢描述:pXrY0GsBN9ZpEwHZ14it:文檔id
方式1:GET 索引/類型/文檔id
GET test_index/test_type/4
方式2:_id文檔唯一的id
GET test_index/test_type/_search
{
"query":{
"match": {
"_id": "4"
}
}
}
⑤多條件查詢
多條件and關系:
#邏輯:and關系 GET test_index/test_type/_search { "query": { "bool": { "must": [ {"match": { "question": "淘寶"}}, {"match": { "question": "軟件"}} ] } } }
GET test_index/test_type/_search
{
"query":{
"bool": {
"must": [
{
"match": {
"name":"中國平安保險(集團)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
]
}
}
}
多條件or關系:
GET test_index/test_type/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"name":"中國平安保險(集團)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
]
}
}
}
多條件and和or關系混合使用:
GET test_index/test_type/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"name":"中國平安保險(集團)股份有限公司"
}
},
{
"term": {
"code": "004"
}
}
],
"must": [
{
"match": {
"count": 2
}
}
]
}
}
}
自定義排序:
GET test_index/test_type/_search
{
"query": {
"bool": {
"must" : [
{
"match" : {
"name" : {
"query" : "中國平安"
}
}
}
],
"adjust_pure_negative": true,
"boost": 1.0
}
},
"_source": {
"includes": ["code", "name"],
"excludes": []
},
"sort": [{
"count": {
"order": "desc"
}
}]
}
⑥指定查詢條數
GET test_index/test_type/_search { "query": { "match": { "question": "淘寶" } }, "from": 1, #指定位移 "size": 5 #指定查詢條數 }
⑦指定查詢返回的字段
GET test_index/test_type/_search { "_source": ["question","nlp"], #返回字段數組 "query": { "match": { "question": "淘寶" } } }
⑧控制加載的字段
GET test_index/test_type/_search { "_source": {"includes": ["question","nlp"],"excludes": ["isSatisfied"]}, "query": { "match": { "question": "淘寶" } } }
⑨通配符
GET test_index/test_type/_search { "_source": {"includes": ["quest*"],"excludes": ["*Date"]}, "query": { "match": { "question": "淘寶" } } }
排序
GET test_index/test_type/_search { "sort": [ { "askTimes": { "order": "desc" } } ], "query": { "match_all": {} } }
前綴匹配
GET test_index/test_type/_search { "query": { "match_phrase_prefix": { "question": "萬科" } } }
返回查詢
GET test_index/test_type/_search { "query": { "range": { "askTimes": { "gte": 10, # "lte": 20 } } } }
wildcard查詢
*代表0個或多個字符
?代表任意一個字符
GET test_index/test_type/_search { "query": { "wildcard": { "question": "萬科*" } } }
模糊查詢
GET test_index/test_type/_search { "query": { "fuzzy": {"question": "萬科"} } }
高亮搜索結果
注:在Kibana中沒有看到效果
GET test_index/test_type/_search { "query": { "match": { "question": "淘寶" } }, "highlight": { "fields": {"question":{}} } }
過濾查詢
GET test_index/test_type/_search { "post_filter": { "term": { "askTimes": 10 } } }
過濾非空
GET test_index/test_type/_search { "query": { "bool": { "filter": { "exists": { "field": "nlp" } } } } }
聚合查詢
sum,min,max,avg,cardinality:求基數,terms:分組
GET /test_index/test_type/_search { "size": 0, "aggs": { "askTimes_of_max": { #自定義名稱 "max": { #最大值 "field": "askTimes" } } } }
符合查詢:待整理
7、檢查noop更新
默認情況下,不更改任何內容的更新會返回“result”:“noop”;
可以通過設置“detect_noop”來禁用此行為:false
PUT test_index/test_type/4
{
"code":"004",
"name":"中國平安保險(集團)股份有限公司",
"count":2,
"tags":["aa","bb"]
}
POST test_index/test_type/4/_update
{
"doc": {
"name":"中國平安保險(集團)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
}
}
如果無論文檔是否存在您都希望腳本運行,即腳本處理初始化文檔而不是upsert元素,設置scripted_upsert為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,如果無論文檔是否存在都希望腳本運行,即腳本處理初始化文檔而不是upsert元素,設置doc_as_upsert為true(文檔5不存在):
POST test_index/test_type/5/_update
{
"doc":{
"count":12
},
"doc_as_upsert":true,
"upsert":{
"count":16
}
}
查詢結果: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、統計索引文檔數量
描述:GET 索引/類型/_count
GET test_index/test_type/_count
②檢測分詞效果
POST test_index/_analyze
{
"analyzer": "ik_max_word",
"text": "我是中國人"
}
