当我尝试输入sat时，我有2个商品名称为“satiny”，它没有出现。
但是，当我键入“sati”时，首先出现“satiny”，然后出现其他产品，然后出现第二个“satiny”产品。
我已经实现了模糊搜索，Edge-ngram，同义词搜索。
这是我的索引:
{"settings": {
"index": {
"analysis": {
"filter": {
"synonym" : {
"type": "synonym",
"synonyms_path": "analysis/synonym.txt"
}
},
"analyzer":
{
"synonym" : {
"tokenizer" : "whitespace",
"filter" : ["lowercase",
"synonym"]
},
"keyword_analyzer": {
"filter": [
"lowercase",
"asciifolding",
"trim"
],
"char_filter": [],
"type": "custom",
"tokenizer": "keyword"
},
"edge_ngram_analyzer": {
"filter": [
"lowercase"
],
"tokenizer": "edge_ngram_tokenizer"
},
"edge_ngram_search_analyzer": {
"tokenizer": "lowercase"
}
},
"tokenizer": {
"edge_ngram_tokenizer": {
"type": "edge_ngram",
"min_gram": 1,
"max_gram": 25,
"token_chars": [
"letter"
]
}
},
"mappings": {
"properties" : {
"firebaseId":{
"type":"text"
},
"name" : {
"type" : "text",
"analyzer" : "synonym"
},
"name_auto" : {
"type": "text",
"fields": {
"edgengram": {
"type": "text",
"analyzer": "edge_ngram_analyzer",
"search_analyzer": "edge_ngram_search_analyzer"
},
"completion": {
"type": "completion"
}
}
},
"category_name" : {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"storeName" : {
"type": "keyword"
},
"sku" : {
"type" : "text"
},
"price" : {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"magento_id" : {
"type" : "text"
},
"seller_id" : {
"type" : "text"
},
"square_item_id" : {
"type" : "text"
},
"square_variation_id" : {
"type" : "text"
},
"typeId" : {
"type" : "text"
}
}
}
}
}
}
}
这是我的查询:
{
"from": 0,
"size": 50,
"query": {
"bool": {
"must": [{
"bool": {
"should": [{
"match_phrase": {
"name_auto.edgengram": "sati"
}
}, {
"match_phrase": {
"name_auto": "sati"
}
}, {
"match": {
"name_auto": "sati"
}
}, {
"match": {
"category_name": {
"query": "sati",
"analyzer": "synonym"
}
}
}, {
"match_phrase": {
"category_name": "sati"
}
}, {
"match": {
"name": {
"query": "sati",
"fuzziness": 2,
"prefix_length": 1
}
}
}]
}
}]
}
}
}
当我键入“sat”时，edge-ngram应该首先启动并向我显示名为“satiny”的产品，然后模糊搜索实现应启动并向我显示具有“sol”或“set”的产品
我得到了部分解决，但我仍然希望所有带有“木炭”的产品名称都首先出现。
最佳答案
问题似乎是您的mappings部分未正确位于settings旁边的顶层。它位于settings.index.analysis内部，因此没有正确定义任何字段。这将有助于正确格式化JSON。
像这样创建索引，它应该可以工作:
{
"settings": {
"index": {
"analysis": {
"analyzer": {
"synonym": {
"tokenizer": "whitespace",
"filter": [
"lowercase"
]
},
"keyword_analyzer": {
"filter": [
"lowercase",
"asciifolding",
"trim"
],
"char_filter": [],
"type": "custom",
"tokenizer": "keyword"
},
"edge_ngram_analyzer": {
"filter": [
"lowercase"
],
"tokenizer": "edge_ngram_tokenizer"
},
"edge_ngram_search_analyzer": {
"tokenizer": "lowercase"
}
},
"tokenizer": {
"edge_ngram_tokenizer": {
"type": "edge_ngram",
"min_gram": 1,
"max_gram": 25,
"token_chars": [
"letter"
]
}
}
}
}
},
"mappings": {
"properties": {
"firebaseId": {

},
