我有一个关于在嵌套对象上执行facet搜索的问题。not_analyzed在ElasticSearch上的嵌套类型?
举个例子,我有以下文件:
tags: [
{
tag: "tag0",
tag_url: "http://xxxxxxx.com/tag/tag0/"
},
{
tag: "tag1",
tag_url: "http://xxxxxx.com/tag/tag1/"
}
],
categories: [
{
category: "cat0",
category_url: "http://xxxxxx.com/category/cat0/"
},
{
category: "cat1",
category_url: "http://xxxxxx.com/category/cat1/"
}
],
,我想对tags.tag
和tags.tag_url
执行方面,所以我做我才能用什么映射创建index:not_analyzed
为嵌套字段?
我已经试过这种映射:
mapping_data[mapping_name]["properties"] = {
"tags.tag" : {
"type": "multi_field",
"fields" : {
"tags.tag": {"type" : "string", "index" : "analyzed", "store": "yes"},
"untouched" : {"type" : "string", "index" : "not_analyzed"}
}
},
"tags.tag_url" : {
"type": "multi_field",
"fields" : {
"tags.tag_url": {"type" : "string", "index" : "analyzed", "store": "yes"},
"untouched" : {"type" : "string", "index" : "not_analyzed"}
}
},
"categories.category" : {
"type": "multi_field",
"fields" : {
"categories.category": {"type" : "string", "index" : "analyzed", "store": "yes"},
"untouched" : {"type" : "string", "index" : "not_analyzed"}
}
},
"categories.category_url" : {
"type": "multi_field",
"fields" : {
"categories.category_url": {"type" : "string", "index" : "analyzed", "store": "yes"},
"untouched" : {"type" : "string", "index" : "not_analyzed"}
}
},
}
和
mapping_data[mapping_name]["properties"] = {
"tags" : {
"type": "nested"
},
"categories" : {
"type": "nested"
},
}
但它并没有给我所需的结果。
使用type:nested
,还是在标记化领域的嵌套,而type: multi_field
不能这样表示,嵌套场not_analyzed
。 (请注意,我在multi_field
变体中使用tags.tag
,但无济于事。)
那么,如何表达映射以实现嵌套文档的构面?
PS:http://www.elasticsearch.org/guide/reference/mapping/nested-type/和http://www.elasticsearch.org/guide/reference/mapping/nested-type/没有产生我需要的结果,因为我没有value_field。
