Elasticsearch query not giving exact match

Question

Am searching elasticsearch with the below match query, which is not giving me the exact match instead its giving some more irrevalant match also.

am using elasticsearch 6.2.3

Please find my query below

get items/_search
{
   "query" : {
      "match" : {
         "code" : "7000-8900"
      }
   }
}

Please find the response am getting it from match query

7000-8900
7000-8002-WK
7000-8002-W

Answer 1

Instead of match you have to use term query, as the documentation describe:

The term query finds documents that contain the exact term specified in the inverted index

So you have to change your query as follow:

get items/_search
{
   "query" : {
      "term" : {
         "code.keyword" : "7000-8900"
      }
   }
}

If you don't get any result there are two possibilities:

• The term searched is not what you think it really is (for example is not trimmed)
• The index has no explicit mapping and the automatic mapping didn't recognize the field code as a string.

---

Note: if the mapping is correct and code is a term field it is possible to use "code". If the mapping was automatic and the mapping recognize it as text you need to use "code.keyword"
