perform full text elastic search

Currently I am trying to perform full text elastic search using the below query

{
 "query": {
"bool": {
  "must": {
    "match": { "city": "mexico city"}
  }
  
}
}
}

I thought the above query would yield the result containing the exact match "Mexico city", however, I am getting the results that contain just Mexico as well. May I know what is wrong with my elastic query please?

>Solution :

That is happening because match query by default use OR operator to search. So anyone term match then it will return results.

You can change operator as shown below:

{
  "query": {
    "match": {
      "city": {
        "query": "mexico city",
        "operator": "and"
      }
    }
  }
}

You can use match_phrase if you want to match exact phrase:

{
  "query": {
    "match_phrase": {
      "city": "mexico city"
    }
  }
}

Above query will return document only where mexico city is matching exactly.
