Contains Not Working In Elasticsearch

elastic search painless script 里面的 contains “不生效”, 还好有 Google

Because Elasticsearch treats those numbers as Longs by default, you need to make sure that you pass a Long to the contains method. The following should work:

GET testdatatype_unit_tests/_search
{
  "size": 100,
  "query": {
    "script": {
      "script": {
        "source": "doc['IntCollection'].values.contains(1L)",
        "lang": "painless"
      }
    }
  }
}
