Multilanguage Support and Empty Aggregation Buckets in Search UI

Elastic Search
1

Hi everyone,

I'm working on an Elasticsearch mapping for a product catalog, and I need help with two key issues:

1. Adding Multilanguage Support

  • Some fields (like nombre and descor_scrap) already use a nested structure with lang and value, but not all fields support multiple languages.
  • The attributes field also has a lang property, and I want to ensure efficient multilingual indexing and searching.
  • What's the best approach to handle multilanguage support across all relevant fields?

2. Empty Aggregation Buckets in Search UI

  • I have attributes as a nested field, and I need to perform dynamic aggregations on it.
  • Running this aggregation directly in Elasticsearch's Dev Console works fine but not in Search UI:
GET products_v2/_search
{
  "size": 0,
  "aggs": {
    "attributes_nested": {
      "nested": {
        "path": "attributes"
      },
      "aggs": {
        "by_key": {
          "terms": {
            "field": "attributes.key",
            "size": 10
          },
          "aggs": {
            "by_value": {
              "terms": {
                "field": "attributes.value",
                "size": 10
              }
            }
          }
        }
      }
    }
  }
}

Any insights would be greatly appreciated! :rocket:

Here is the current mapping:
