how to write Elastic search query for exact match for a string

Question

I am using kibanna I am trying to put filter on a field container_name = "armenian" but I have other container names with following names

1. armenian_alpha
2. armenian_beta
3. armenian_gama
4. armenian1
5. armenian2

after putting the filter , search query in kibanna becomes

{
  "query": {
    "match": {
      "container_name": {
        "query": "armenian",
        "type": "phrase"
      }
    }
  }
}

But the output searches logs for all containers , as I can see the Elastic search query is using a pattern matching

How can I put an exact match with the string provided and avoid the rest ?

You can try out with term query. Do note that it is case sensitive by default unless you specify with case_insensitive equals to true. Also, if your container_name is a text field type instead of keyword field type, do add the .keyword after the field name. Otherwise, ignore the .keyword.

Example:

GET /_search
{
  "query": {
    "term": {
      "container_name.keyword": {
        "value": "armenian"
      }
    }
  }
}
