# Elasticsearch 查询相关
## 根据商品ID查询
```json
GET /uat_spu/_search
{
"query": {
"term": {
"_id": "3588136"
}
}
}
```
## 查label_id
```json
GET /uat_spu/_search
{"query":{"bool":{"must":[{"term":{ "platform_sku_essaone": true }},{"term":{"label_id_list":166}}]}}}
```
## collapse折叠
```json
GET /spu/_search
{
"_source": ["_id", "name_zh", "goods_id", "*"],
"size": 1000,
"query": {
"match": {
"name_zh": {
"query": "园艺"
}
}
},
"collapse": {
"field": "goods_id", // 按 goods_id 字段折叠分组
"inner_hits": {
"_source": ["_id"],
"name": "top_docs", // 自定义内部结果名称
"size": 3, // 每组取1个文档
"sort": [{"_score": "desc"}] // 按评分降序排序
}
},
"sort": ["_score"] // 确保外层排序兼容折叠功能
}
```
## 在架、某平台商品数
```json
GET /uat_spu/_search
{
"track_total_hits": 100000,
"query": {
"bool": {
"filter": [
{
"term": {
"platform_sku_essaone": true
}
},
{
"term": {
"platform_rule_essaone": true
}
},
{
"terms": {
"goods_copyright": [
"1",
"2",
"3"
]
}
}
]
}
}
}
```
## ID查询
```json
GET /uat_spu/_search
{
"query": {
"term": {
"_id": "3302275"
}
}
}
```
## 商品名搜索
```json
GET /spu/_search
{
"_source": {
},
"size": 1000,
"query": {
"match": {
"name_zh": {
"query": "园艺工具四件套",
"boost": 111.0
}
}
},
"aggs" :{
"goods_agg": {
"terms": {
"field": "goods_id",
"size": 100
},
"aggs": {
"top_hits": {
"top_hits": {
"size": 1,
"sort": [{"_score": "desc"}]
}
}
}
}
}
}
```
## phrase搜索
```json
GET /uat_spu/_search
{
"_source":["id","goods_id","name_zh"],
"query":{
"multi_match": {
"_name": "base_query",
"fields": [
"name_zh^2.0",
"goods_keyword_zh^1.0",
"category_name_zh^1.0",
"sale_category_keyword_zh^1.0",
"sub_name_zh^1.0"
],
"query": "戏水玩具"
}
}
}
```
## aggs聚合查询
```json
GET /spu/_search
{
"_source": {
"excludes": [
"embedding_name_zh",
"embedding_name_ru", "*"
],
"includes": ["_id", "name_zh"]
},
"size": 1000,
"query": {
"match": {
"name_zh": {
"query": "园艺"
}
}
},
"aggs" :{
"goods_agg": {

"field": "goods_id",
"size": 100
},
"aggs": {
"top_hits": {
"top_hits": {
"size": 1,
"sort": [{"_score": "desc"}]
}
}
}
}
}
}
```
## 检查某个字段是否有值
```json
GET /uat_spu/_search
{
"track_total_hits": true,
"size": 0, // 不返回 hits，只返回总数
"query": {
"exists": {
"field": "goods_keyword_zh"
}
}
}
```
如果是nested字段，要这么查：
```json
GET /uat_spu/_search
{
"track_total_hits": true,
"size": 0, // 只看总数
"query": {
"nested": {
"path": "embedding_pic_h14",
"query": {
"exists": {
"field": "embedding_pic_h14.vector" // 或 url，只要子文档里任意字段有值
}
}
}
}
}
```
```json
```
## 分词测试
### ik_smart分词器
```json
POST spu/_analyze
{
"analyzer": "ik_smart",
"text": "14寸第4代-眼珠实身冰雪公仔带手动大推车,搪胶雪宝宝"
}
```
### ik_max_word分词器
```json
POST spu/_analyze
{
"analyzer": "ik_max_word",
"text": "14寸第4代-眼珠实身冰雪公仔带手动大推车,搪胶雪宝宝"
}
```

# 一些问题
有一个商品，只命中了"玩具"、没有命中"遥控"，两个词命中一个词（注意是所有的字段 总共只命中一个词，玩具命中多次，但是没有任何一个字段有"遥控"），minimum_should_match应该没有达到76%吧，76%是按照什么算的？为什么命中了这个查询条件？
```json
"multi_match": {
"_name": "base_query",
"fields": [
"name_zh^2.0",
"goods_keyword_zh^1.0",
"category_name_zh^1.0",
"sale_category_keyword_zh^1.0",
"sub_name_zh^1.0"
],
"minimum_should_match": "76%",
"query": "遥控玩具",
"tie_breaker": 0.3
}
```
tie_breaker 导致
```json
GET /spu/_search
{

"embedding_name_zh",
"embedding_name_ru", "*"
],
"includes": ["_id", "name_zh"]
