Search template based on list

[pszemesy (Peter Szemesy)]

Hi All,

I have an index (contains translations) with the following mappings:

document_name: keyword,
...
EN: {
  content: text,
  stored_by: keyword,
  stored_at: date,
  ...
}
<<lang code>>: {
  content: text,
  stored_by: keyword,
  stored_at: date,
  ...
} 

Till now the 3rd party application has searched on the following way:

GET translation-*/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match" : {
            "EN.content": {
              "query": <<query text>>,
              ...
            }
          }
        }
      ],
      "should": [
        {
          "exists": {
            "field": <<language code 1>>
          }
        },
        {
          "exists": {
            "field": <<language code 2>>
          }
        },
        {
          ...
        },
        {
          "exists": {
            "field": <<language code n>>
          }
        }
      ],
      "minimum_should_match": 1
    }
  },
  "_source": [
    "document_name",
    <<language code 1>>,
    <<language code 2>>,
    ...,
   <<language code n>>
  ]
}

So I would like to create a search template where the parameters are the following:

• query text
• list of language codes

Are there any way to create something like that? Thanks
