带有分组 query_string 的 Elasticsearch

Question

{
   "query":
   {
      "query_string" :
      {
         "query" : "((name:the_search_phrase) OR (keywords:the_search_phrase)) AND (city:Sydney, Australia)"
      }
   }
}

New to elasticsearch. Building the JSON as per the documentation here: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html

The query runs, however, results with city other that Sydney, Australia are returned too. Why the AND part is not working?

I want the search phrase to match against either or both name, keywords but the city should be strictly Sydney.

Answer 1

What you are doing is a full text query. city:Sydney, Australia seems to be a filter query. Like a WHERE clause in a SQL. You are better off using a filter query for that.

Look at the boolean query for examples,

Something like this perhaps,

    {
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "query": "the_search_term",
            "fields": [
              "name",
              "keywords"
            ]
          }
        }
      ],
      "filter": [
        {
          "match": {
            "city": "Sydney, Australia"
          }
        }
      ]
    }
  }
}
