我试图从ElasticSearch查询中检索嵌套数据，基本上试图从Movie模型中获取：
title
ratings
categories
现在，我尝试了2个轮胎设置，但两者都只提供电影 Headers ，而不是评级或类别 . 例如 . 索引似乎只是：
curl -X POST "http://localhost:9200/movies/_search?pretty=true" -d '
{
"query" : { "query_string" : {"query" : "t*"} },
"facets" : {
"categories" : { "terms" : {"field" : "categories"} }
}
}
'
{
"took" : 16,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 1.0,
"hits" : [ {
"_index" : "movies",
"_type" : "movie",
"_id" : "13",
"_score" : 1.0, "_source" : {"description":null,"id":13,"title":"Tiny Plastic Men"}
}, {
"_index" : "movies",
"_type" : "movie",
"_id" : "32",
"_score" : 1.0, "_source" : {"description":null,"id":32,"title":"The Extreme Truth"}
}, {
"_index" : "movies",
"_type" : "movie",
"_id" : "39",
"_score" : 1.0, "_source" : {"description":null,"id":39,"title":"A Time of Day"}
} ]
},
"facets" : {
"categories" : {
"_type" : "terms",
"missing" : 3,
"total" : 0,
"other" : 0,
"terms" : [ ]
}
}
这是我的电影模型：
class Movie :categorizations
belongs_to :user
has_many :ratings
mapping do
indexes :id, type: 'integer'
indexes :title, boost: 40
indexes :description, analyzer: 'snowball'
indexes :categories do
indexes :id, type: 'integer'
indexes :name, type: 'string', index: 'not_analyzed'
end
indexes :ratings do
indexes :id, type: 'integer'
indexes :stars, type: 'integer'
end
end
end
我的搜索实验的分支在这里：https://github.com/mulderp/moviedb/tree/categories
我怎样才能为搜索工作制作方面，例如类型 - >评级 .

你're not actually indexing the categories or ratings: they'在映射中，但轮胎的默认实现
to_indexed_json只调用activerecord提供的to_json方法 .例如，您需要覆盖它以包含类别/评级信息
