這裏,似乎你想要做什麼的設置。我使用了相同的基本代碼作爲最後的答案,但在索引定義中使用index_analyzer
和search_analyzer
如下:
curl -XDELETE "http://localhost:9200/my_index"
curl -XPUT "http://localhost:9200/my_index" -d'
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0,
"analysis": {
"filter": {
"snowball": { "type": "snowball", "language": "English" },
"english_stemmer": { "type": "stemmer", "language": "english" },
"english_possessive_stemmer": { "type": "stemmer", "language": "possessive_english" },
"stopwords": { "type": "stop", "stopwords": [ "_english_" ] },
"worddelimiter": { "type": "word_delimiter" }
},
"tokenizer": {
"nGram": { "type": "nGram", "min_gram": 3, "max_gram": 20 }
},
"analyzer": {
"custom_analyzer": {
"type": "custom",
"tokenizer": "nGram",
"filter": [
"stopwords",
"asciifolding",
"lowercase",
"snowball",
"english_stemmer",
"english_possessive_stemmer",
"worddelimiter"
]
},
"custom_search_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"stopwords",
"asciifolding",
"lowercase",
"snowball",
"english_stemmer",
"english_possessive_stemmer",
"worddelimiter"
]
}
}
}
},
"mappings": {
"posts": {
"properties": {
"title": {
"type": "string",
"analyzer": "custom_analyzer",
"boost": 5
},
"seller": {
"type": "nested",
"properties": {
"firstName": {
"type": "string",
"index_analyzer": "custom_analyzer",
"search_analyzer": "custom_search_analyzer",
"boost": 3
}
}
}
}
}
}
}'
然後加入測試文檔
curl -XPUT "http://localhost:9200/my_index/posts/1" -d'
{"title": "post", "seller": {"firstName":"Test 1"}}'
curl -XPUT "http://localhost:9200/my_index/posts/2" -d'
{"title": "post", "seller": {"firstName":"Test 2"}}'
curl -XPUT "http://localhost:9200/my_index/posts/3" -d'
{"title": "post", "seller": {"firstName":"Test 3"}}'
,然後在幾個match
查詢一個bool
,其中一個是multiword query,似乎完成你想要什麼:
curl -XPOST "http://localhost:9200/my_index/_search" -d'
{
"query": {
"bool": {
"must": [
{
"match": {
"title": "post"
}
},
{
"nested": {
"path": "seller",
"query": {
"match": {
"seller.firstName": {
"query": "Test 3",
"operator": "and"
}
}
}
}
}
]
}
}
}'
...
{
"took": 5,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 6.8380365,
"hits": [
{
"_index": "my_index",
"_type": "posts",
"_id": "3",
"_score": 6.8380365,
"_source": {
"title": "post",
"seller": {
"firstName": "Test 3"
}
}
}
]
}
}
這裏是我使用的代碼:

這是否解決問題了嗎?
