我有带有属性的产品。例如“名称”,“品牌”,“颜色”,“类别”,“尺寸”。当我按词组(例如“ black jacket puma”)搜索产品时,除了与“ brand” =“ puma”,“ color” =“ black”,“ category” =“ jacket”或“ name” =完全匹配“黑色彪马外套”,我也有部分搭配的产品。我的查询是:
'match' => [
'message' => [
'query' => "black puma jacket"
'operator' => 'and'
]
]
我也尝试过以下查询:
'multi_match' => [
'fields' => [
'brand',
'color',
'name'
],
'query' => 'puma black jacket',
]
我的查询出了什么问题?

根据您的映射和要求,我认为cross_fields可能会对您有所帮助。
仅具有2个属性(颜色和类别)的示例:
发布一些文档:
POST my_index/_doc/1
{
"color": "black",
"category": "1"
}
POST my_index/_doc/2
{
"color": "black",
"category": "2"
}
POST my_index/_doc/3
{
"color": "black",
"category": "3"
}
POST my_index/_doc/4
{
"color": "1",
"category": "jacket"
}
POST my_index/_doc/5
{
"color": "2",
"category": "jacket"
}
POST my_index/_doc/6
{
"color": "3",
"category": "jacket"
}
POST my_index/_doc/6
{
"color": "3",
"category": "jacket"
}
POST my_index/_doc/7
{
"color": "black",
"category": "jacket"
}
POST my_index/_doc/8
{
"color": "black",
"category": "jacket"
}
您的搜索查询如下:
GET my_index/_search
{
"query": {
"multi_match": {
"query": "black jacket",
"fields": [],
"type": "cross_fields",
"operator": "and",
"analyzer": "standard"
}
}
}
结果:
{
"took" : 0,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 3,
"relation" : "eq"
},
"max_score" : 1.2192403,
"hits" : [
{
"_index" : "my_index",
"_type" : "_doc",
"_id" : "7",
"_score" : 1.2192403,
"_source" : {
"color" : "black",
"category" : "jacket"
}
},
{
"_index" : "my_index",
"_type" : "_doc",
"_id" : "8",
"_score" : 1.2192403,
"_source" : {
"color" : "black",
"category" : "jacket"
}
}
]
}
如您所见,我们没有得到所有其他文档的部分匹配为 black 或 jacket
希望获得帮助

根据您的要求,我将品牌,颜色和类别分组为一个字段,然后应用词组匹配。您需要修改产品映射
PUT /products
{
"mappings":{
"properties":{
"brand": {
"type": "text",
"copy_to": "name",
...
},
"color": {
"type": "text",
"copy_to": "name",
...
},
"category": {
"type": "text",
"copy_to": "name",
...
},
"name": {
"type": "text"
},
...
}
}
}
在名称字段上使用词组匹配进行搜索
GET /products/_search
{
"query":{
"match_phrase": {
"name": {
"query": {
"name": "black puma jacket",
"slop": 1
}
}
}
}
}
