I have a index something like this: ![Screenshot 2023-06-10 191513](https://us1.discourse-cdn.com/elastic/original/3X/e/6/e698404d44244af60d5852e1e82ab6c3634f5347.png) All countries' names, along with their populations, exist in my index. Since Kibana does not allow us to use the countries' normal names, I have to add unique country codes such as FR, KR, TR.... Could it possible? How to cope with it? ---

I guess it's for maps when you want to highlight the country and you don't have a geo point. You can provide a synonym list which converts each country name as its ISO code (I d apply this analyzer to a new sub field like country.code) or use an ingest pipeline to create a new field like country\_code. . ---

On kibana, when i try to create a choropleth map, if i choose the world countries option; ![Screenshot 2023-06-11 135249](https://us1.discourse-cdn.com/elastic/original/3X/a/5/a514961b9032a9fb2faa895132d447dcd6dc1de0.jpeg) it displays this message. ---

I shouldn't convert country fields to their ISO code. I must add extra fields for this. I guess i should use enrichment data but I don't know how can i provide this. Could you explain gradually? ---

Some doc about synonyms here: [Synonym token filter | Elasticsearch Guide [8.8] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-synonym-tokenfilter.html) Some doc about ingest pipelines here and the enrich processor here: [Enrich your data | Elasticsearch Guide [8.8] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/ingest-enriching-data.html) Hope this helps. ---

Another option is a [runtime lookup field](https://www.elastic.co/guide/en/elasticsearch/reference/current/runtime-retrieving-fields.html#lookup-runtime-fields) might be a good way to test see if it works for you, you might need to add it to the mapping not data view for it to work in a map ...you need to check that, I have not tried that yet. Probably the best approach is the enrich processor that @dadoonet suggested. ---
