How to do a wildcard or regex match on _id in elasticsearch?

Question

From below sample elasticsearch data I want to apply wildcard say *.000ANT.* on _id so as to fetch all docs whose _id contains 0

Answer 1

This is just an extension on Andrei Stefan's answer

{
  "query": {
    "script": {
      "script": "doc['_id'][0].indexOf('000ANT') > -1"
    }
  }
}

Note: I do not know the performance impact of such a query, most probably this is a bad idea. Use with caution and avoid if possible.
