我正在尝试使用空格进行通配符查询。它很容易根据术语而不是根据字段匹配单词。
我已经阅读了说明我需要将该字段设置为not_analyzed的文档，但是设置了此类型后，该字段不返回任何内容。
这是基于术语的映射：
{
"denshop" : {
"mappings" : {
"products" : {
"properties" : {
"code" : {
"type" : "string"
},
"id" : {
"type" : "long"
},
"name" : {
"type" : "string"
},
"price" : {
"type" : "long"
},
"url" : {
"type" : "string"
}
}
}
}
}
}
这是完全相同的查询不返回任何内容的映射：
{
"denshop" : {
"mappings" : {
"products" : {
"properties" : {
"code" : {
"type" : "string"
},
"id" : {
"type" : "long"
},
"name" : {
"type" : "string",
"index" : "not_analyzed"
},
"price" : {
"type" : "long"
},
"url" : {
"type" : "string"
}
}
}
}
}
}
查询在这里：
curl -XPOST http://127.0.0.1:9200/denshop/products/_search?pretty -d '{"query":{"wildcard":{"name":"*test*"}}}'
该not_analyzed属性的响应：
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
没有not_analyzed的响应：
{
"took" : 4,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 5,
"max_score" : 1.0,
"hits" : [ {
...
编辑：添加请求的信息
这是文件清单：
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 5,
"max_score" : 1.0,
"hits" : [ {
"_index" : "denshop",
"_type" : "products",
"_id" : "3L1",
"_score" : 1.0,
"_source" : {
"id" : 3,
"name" : "Testovací produkt 2",
"code" : "",
"price" : 500,
"url" : "http://www.denshop.lh/damske-obleceni/testovaci-produkt-2/"
}
}, {
"_index" : "denshop",
"_type" : "products",
"_id" : "4L1",
"_score" : 1.0,
"_source" : {
"id" : 4,
"name" : "Testovací produkt 3",
"code" : "",
"price" : 666,
"url" : "http://www.denshop.lh/damske-obleceni/testovaci-produkt-3/"
}
}, {
"_index" : "denshop",
"_type" : "products",
"_id" : "2L1",
"_score" : 1.0,
"_source" : {
"id" : 2,
"name" : "Testovací produkt",
"code" : "",
"price" : 500,
"url" : "http://www.denshop.lh/damske-obleceni/testovaci-produkt/"
}
}, {
"_index" : "denshop",
"_type" : "products",
"_id" : "5L1",
"_score" : 1.0,
"_source" : {
"id" : 5,
"name" : "Testovací produkt 4",
"code" : "",
"price" : 666,
"url" : "http://www.denshop.lh/damske-obleceni/testovaci-produkt-4/"
}
}, {
"_index" : "denshop",
"_type" : "products",
"_id" : "6L1",
"_score" : 1.0,
"_source" : {
"id" : 6,
"name" : "Testovací produkt 5",
"code" : "",
"price" : 666,
"url" : "http://www.denshop.lh/tricka-tilka-tuniky/testovaci-produkt-5/"
}
} ]
}
}
如果没有not_analyzed它，则返回：
curl -XPOST http://127.0.0.1:9200/denshop/products/_search?pretty -d '{"query":{"wildcard":{"name":"*testovací*"}}}'
但是不可以（请注意星号前的空格）：
curl -XPOST http://127.0.0.1:9200/denshop/products/_search?pretty -d '{"query":{"wildcard":{"name":"*testovací *"}}}'
当我将not_analyzedto添加到映射时，无论我在通配符查询中输入什么内容，它都不会返回任何匹配。
添加一个自定义分析器，该文本应小写。然后，在您的搜索查询中，在将文本传递给它之前，请先在客户端应用程序中将其小写。
同样，为了保留原始分析链，我在您的name字段中添加了一个子字段，该子字段将使用自定义分析器。
PUT /denshop
{
"settings": {
"analysis": {
"analyzer": {
"keyword_lowercase": {
"type": "custom",
"tokenizer": "keyword",
"filter": [
"lowercase"
]
}
}
}
},
"mappings": {
"products": {
"properties": {
"name": {
"type": "string",
"fields": {
"lowercase": {
"type": "string",
"analyzer": "keyword_lowercase"
}
}
}
}
}
}
}
该查询将在子字段上工作：
GET /denshop/products/_search
{
"query": {
"wildcard": {
"name.lowercase": "*testovací *"
}
}
}
