Elasticsearch: Wildcard query

“wildcard” query supports wild cards.

For Example,

Wildcard ‘*’ matches zero/more characters.
Wildcard ‘?’ matches one character.

GET /books/titles/_search
{
  "query":{
    "wildcard":{
      "title" : "L*"
    }
  }
}

Above query matches all documents, where title starts with L.

            }
         },
         {
            "_index": "books",
            "_type": "titles",
            "_id": "7",
            "_score": 1,

               "title": "Life, Love, Laughter: Celebrating Your Existence"
            }
         }
      ]
   }
}
