Elasticsearch前缀完全匹配

Question

i have text fields like above

elastic|b|c
elastic,search|b|c
elastic,search,prefix|b|c

I want to query on this string with prefix. And the query is

aggs":{  
   "field":{  
      "filter":{  
         "match":{  
            "field":{  
               "type":"prefix",
               "query":"elastic|"
            }
         }
      },
      "aggs":{  
         "field":{  
            "terms":{  
               "field":"textField",
               "size":255
            }
         }
      }
   }
}
},
"

and this query return all texts below in the example. Do i need extra analyzer or token filter on texts? How can i exact match search with prefix on elastic ?

Answer 1

you can achieve that by using wildcards in elasticsearch.

{
  "query": {
"wildcard": {
      "textField": {
        "value": "elastic*"
      }
    }
  }
}
