有没有办法做得更好？
这个想法是建议像亚马逊搜索框建议那样的词（搜索时输入）。
我有一个可行的解决方案，但我认为有更好的解决方案。
设置
PUT store
{
"settings": {
"max_shingle_diff" : 50,
"analysis": {
"analyzer": {
"suggestions": {
"type": "custom",
"tokenizer": "standard",
"filter": ["suggestions_shingle", "lowercase"]
}
},
"filter": {
"suggestions_shingle": {
"type": "shingle",
"min_shingle_size": 2,
"max_shingle_size": 50
}
}
}
}
}
分析仪
POST store/_analyze
{
"analyzer": "suggestions",
"text": "Telefon mobil Samsung S10"
}
映射
POST store/_mappings
{
"properties": {
"name": {
"type": "text",
"fields": {
"suggestions": {
"type": "text",
"analyzer": "suggestions",
"fielddata": true
}
}
}
}
}
文件
POST store/_doc
{
"name": "Apple iPhone X (64GB) - Silver"
}
POST store/_doc
{
"name": "Apple iPhone 11 (128GB) - White"
}
POST store/_doc
{
"name": "Apple iPhone X (64 GB) - Space Grey",
}
POST store/_doc
{
"name": "Apple iPhone 6s 32GB Rose Gold",
}
POST store/_doc
{
"name": "Samsung Galaxy A10 Dual-SIM 32GB",
}
POST store/_doc
{
"name": "Samsung Galaxy A70 Dual-SIM 128GB",
}
POST store/_doc
{
"name": "Samsung Galaxy S10 128 GB",
}
POST store/_doc
{
"name": "Samsung Galaxy M30s Black"
}
POST store/_doc
{
"name": "Samsung Galaxy A20e"
}
和搜索
GET store/_search
{
"size": 0,
"aggs":{
"description_suggestions":{
"terms":{
"field":"name.suggestions",
"include":"ip(.*)",
"size": 4
}
}
}
}
结果
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 4,
"relation" : "eq"
},
"max_score" : null,
"hits" : [ ]
},
"aggregations" : {
"description_suggestions" : {
"doc_count_error_upper_bound" : 0,
"sum_other_doc_count" : 3,
"buckets" : [
{
"key" : "iphone",
"doc_count" : 2
},
{
"key" : "iphone 11",
"doc_count" : 1
},
{
"key" : "iphone 11 128gb",
"doc_count" : 1
},
{
"key" : "iphone 11 128gb white",
"doc_count" : 1
}
]
}
}
}
我不认为这是最好的解决方案。有没有办法优化这个？
