一、引
经过上述章节的阐述，最后实操一个小小的CRUD Demo，感受一下，ES为我们带来的便利。
二、创建索引
PUT demo_goods
{
"mappings": {
"doc":{
"properties":{
"category":{
"type":"keyword"
},
"spu_name":{
"type":"text",
"analyzer":"ik_smart"
},
"title":{
"type":"text",
"analyzer":"ik_smart"
},
"price":{
"type":"scaled_float",
"scaling_factor": 100
},
"img":{
"type":"keyword",
"index":false
}
}
}
}
}
三、插入记录
POST demo_goods/doc/
{
"category":"耳机",
"spu_name":"Airpods",
"title":"Apple Airpods配充电盒 Apple蓝牙耳机 适用iphone/ipad/Apple Watch",
"price":1146.00,
"img":"xxx.jpg"
}
POST demo_goods/doc/
{
"category":"耳机",
"spu_name":"网易云音乐 ME05TWS",
"title":"网易云音乐【零感佩戴】 真无线蓝牙耳机双耳 半入耳式运动跑步游戏耳机通用于苹果华为小米手机",
"price":159.00,
"img":"xxx.jpg"
}
POST demo_goods/doc/
{
"category":"耳机",
"spu_name":"漫步者 LolliPods",
"title":"漫步者（EDIFIER） LolliPods真无线蓝牙耳机 半入耳式耳机 音乐耳机 通用苹果华为小米手机 萝莉pods",
"price":238.00,
"img":"xxx.jpg"
}
POST demo_goods/doc/
{
"category":"白酒",
"spu_name":"茅台 飞天",
"title":"茅台飞天 酱香型白酒",
"price":999.00,
"img":"xxx.jpg"
}
POST demo_goods/doc/
{
"category":"白酒",
"spu_name":"五粮液第八代",
"title":"五粮液52度普五第八代款",
"price":1399.00,
"img":"xxx.jpg"
}
四、查询记录
GET demo_goods/_search
{
"query": {
"multi_match": {
"query" : "音乐耳机",
"fields": ["spu_name","title"]
}
}
}
GET /demo_goods/_search
{
"query": { "match_all": {} },
"from": 0,
"size": 20
}
GET demo_goods/doc/ShL0LXcBUkVyXtlB_mOR
五、更新记录
POST demo_goods/doc/UBItLncBUkVyXtlBk2O0
{
"category": "白酒",
"spu_name": "五粮液第八代",
"title": "五粮液52度普五第八代款",
"price": 1399,
"img": "xxx.jpg"
}
六、删除记录
DELETE demo_goods/doc/UxI7LncBUkVyXtlBZGOO
POST demo_goods/_delete_by_query
{
"query": {
"match_all": {}
}
}
七、总结
附上我翻译成Java代码所用的依赖...
ES以及其生态，还远不于此。上官网吧：https://www.elastic.co
ES(六) ElasticSearch搜索原理
