1.マッピングのコンテンツを変更します
古いマッピングは次のとおりです。多くのフィールドのインデックスとdoc_valuesがfalseであることがわかります。これらのフィールドは、取得とコンテンツの表示に使用されません。
{
"product" : {
"mappings" : {
"properties" : {
"attrs" : {
"type" : "nested",
"properties" : {
"attrId" : {
"type" : "long"
},
"attrName" : {
"type" : "keyword",
"index" : false,
"doc_values" : false
},
"attrValue" : {
"type" : "keyword"
}
}
},
"brandId" : {
"type" : "long"
},
"brandImg" : {
"type" : "keyword",
"index" : false,
"doc_values" : false
},
"brandName" : {
"type" : "keyword",
"index" : false,
"doc_values" : false
},
"catelogId" : {
"type" : "long"
},
"catelogName" : {
"type" : "keyword",
"index" : false,
"doc_values" : false
},
"hasStock" : {
"type" : "boolean"
},
"hotScore" : {
"type" : "long"
},
"saleCount" : {
"type" : "long"
},
"skuId" : {
"type" : "long"
},
"skuImg" : {
"type" : "keyword",
"index" : false,
"doc_values" : false
},
"skuPrice" : {
"type" : "keyword"
},
"skuTitle" : {
"type" : "text",
"analyzer" : "ik_smart"
},
"spuId" : {
"type" : "keyword"
}
}
}
}
}
次のように変更し、新しいマッピングgulimall_productを作成します（すべてfalseを削除します）
PUT gulimall_product
{
"mappings" : {
"properties" : {
"attrs" : {
"type" : "nested",
"properties" : {
"attrId" : {
"type" : "long"
},
"attrName" : {
"type" : "keyword"
},
"attrValue" : {
"type" : "keyword"
}
}
},
"brandId" : {
"type" : "long"
},
"brandImg" : {
"type" : "keyword"
},
"brandName" : {
"type" : "keyword"
},
"catelogId" : {
"type" : "long"
},
"catelogName" : {
"type" : "keyword"
},
"hasStock" : {
"type" : "boolean"
},
"hotScore" : {
"type" : "long"
},
"saleCount" : {
"type" : "long"
},
"skuId" : {
"type" : "long"
},
"skuImg" : {
"type" : "keyword"
},
"skuPrice" : {
"type" : "keyword"
},
"skuTitle" : {
"type" : "text",
"analyzer" : "ik_smart"
},
"spuId" : {
"type" : "keyword"
}
}
}
}2.古いデータのインデックスを再作成します。これは、データの移行に相当します。
POST _reindex
{
"source": {
"index": "product"
},
"dest": {
"index": "gulimall_product"
}
}3.3。
そして、古いデータをデータに挿入します
GET product/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"skuTitle": "华为"
}
}
],
"filter": [
{
"term": {
"hasStock": "false"
}
},
{
"terms": {
"brandId": [
"6",
"10"
]
}
},{
"nested": {
"path": "attrs",
"query": {
"bool": {
"must": [
{
"term": {
"attrs.attrId": {
"value": "1"
}
}
}
]
}
}
}
},{
"range": {
"skuPrice": {
"gte": 0,
"lte": 4000
}
}
}
]
}
},
"sort": [
{
"skuPrice": {
"order": "desc"
}
}
],
"from": 0,
"size": 2,
"highlight": {
"fields": {"skuTitle": {}},
"pre_tags": "<b style='color:red'>",
"post_tags": "</b>"
},
"aggs": {
"brand_agg": {
"terms": {
"field": "brandId",
"size": 10
},
"aggs": {
"brandNameAgg": {
"terms": {
"field": "brandName",
"size": 10
}
},
"brandImgAgg": {
"terms": {
"field": "brandImg",
"size": 10
}
}
}
},
"catalogAgg": {
"terms": {
"field": "catelogId",
"size": 10
},
"aggs": {
"catalogNameAgg": {
"terms": {
"field": "catelogName",
"size": 10
}
}
}
}
}
}3.集計分析を追加します
次の3つが含まれます。分類されたブランド属性。属性は次のように集約属性です。最初にネストを追加してパスを指定します。
GET gulimall_product/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"skuTitle": "华为"
}
}
],
"filter": [
{
"term": {
"hasStock": "false"
}
},
{
"terms": {
"brandId": [
"6",
"10"
]
}
},{
"nested": {
"path": "attrs",
"query": {
"bool": {
"must": [
{
"term": {
"attrs.attrId": {

}
}
}
]
}
}
}
},{
"range": {

}
}
}
]
}
},
"sort": [
{

}
}
],

}
}
}
},
"attrAgg": {

},
"aggs": {
"attrIdAgg": {

"aggs": {
"attrNameAgg": {
"terms": {
"field": "attrs.attrName",
"size": 10
}
}
}
}
}
}
}
