Parent-Child Mapping

• Requires mapping at the time of index creation or using update-mapping

• Creating new index with two types for parent-child relationship:

  curl -XPUT 'localhost:9200/politics?pretty=true' -d '
  {
   "mappings": {
     "party": {},
     "supporter": {
       "_parent": {
         "type": "party" 
       }
     }
   }
  }'
