ElasticSearch：对 IN 查询使用查询字符串

Question

I'm trying to do something similar to an IN statement in SQL, eg

SELECT * FROM es_index WHERE in_col in ('v1', 'v2', 'v3') AND match_col='v4';

I need to do this with a query string (this is a must) in ElasticSearch since only this function is exposed for me, so I tried out

// GET /_search
{
  "query": {
    "query_string": {
      "query": "(in_col: [v1, v2, v3]) AND (match_col:v4)"    
    }
  }
}

But it gave me a parsing error

Cannot parse 'in_col: [v1, v2, v3]': Encountered \" \"]\" \"] \"\" at line x, column y.\nWas expecting:\n    \"TO\" ...\n

Any idea?

IN is basically an OR condition so you can do it like this

{
  "query": {
    "query_string": {
      "query": "in_col:(v1 OR v2 OR v3) AND match_col:v4"    
    }
  }
}
