Elasticsearch – combine ids query with must_not clause

Question

I’d like to combine ids query with must_not clause. I’m using (re)tire gem with rails application.

I’m doing something like this:

query do
  ids ["foo", "bar", "test"]
end

Which works. However, when I’m trying to combine it with must_not clause, I’m getting error – must_not works only withing boolean scope, which does not include ids query. Is there any way to combine that two queries?

The ES query that you need to use is this one:

GET /some_index/some_type/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "ids": {
            "values": ["foo", "bar", "test"]
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "name": "whatever"
          }
        }
      ]
    }
  }
}

So, you need boolean scope, a must with your ids and a must_not with your must not match queries.
