Terms Lookup + sort


(Sverdier) #1

Hi,

I want to sort users by created_at of likers it's possible with terms Lookup ?

PUT /newsfeed/feed/1
{
 "likers" : [
   {
     "id" : "1",
     "created_at": "2017-04-16T19:02:26Z"
   },
   {
     "id" : "2",
     "created_at": "2017-04-16T19:02:26Z"
   }
 ]
}

GET /users/user/_search
{
      "query":{
         "terms":{
            "id":{
               "index":"newsfeed",
               "type":"feed",
               "id":"1",
               "path":"likers.id"
            }
         }
      }
}

Not through the terms lookup functionality. You can think of that as merely grabbing the list of terms to filter from a document, rather than from the query body supplied as part of the request.

But you can add a sort element to your query which does the sorting:

GET /users/user/_search
{
      "query":{
         "terms":{
            "id":{
               "index":"newsfeed",
               "type":"feed",
               "id":"1",
               "path":"likers.id"
            }
         }
      },
      "sort" : [
          { "likers.id" : {"order" : "asc"}},
          "_score"
      ],
}

Note that unless that first document is using Nested Documents (you can also read more here) your relationships in the document may not be preserved like you think they are.
