Elasticsearch term aggregate query on array field

I was using elasticsearch 1.7.3 and my term aggregate query

     "aggregations" : {"tagsList" : {  "terms" : {
     "field" : "tagsList.tagsList_sort",
     "size" : 100,
     "order" : {
           "_term" : "asc"
       },
      "include" : "((?i).*accoun.*)"  }}

Recently I upgraded my es version to 2.3.x and above query is not working. Please suggest similar query for esv2.3.x
