solr

问题 I am using apache solr for text search . I have nested document structure . This is one.json file : { "id": "1", "info": { "first_name": "John", "last_name": "Doe", "gender": "male" } } I created a solr core and posted one.json in it.Solr indexed and flattened the above document's nested structure , I guess for better indexing in following form: { "id":["1"], "info.first_name":["John"], "info.last_name":["Doe"], "info.gender":["male"] } Now, when I make the search query,the result is in

问题 So I have many items that can be part of many different pages. So here is the simplified models: class Page #we just need the id for this question end class Item embeds_many :page_usages end class PageUsage field :position, :default => 0 embedded_in :item belongs_to :page end So the page_usage is holding the position of the items on every page.
