Localized highlighting issue

Elastic Stack Elasticsearch
1

Hi all,

so here's the thing: we have some products that have their name
localized in several languages. The name is defined in Elasticsearch
as following:

===
name: {
de: "some german text",
en: "some english text",
nl: "some dutch text"
}

It all works good - if I have to search I search not in the "name"
field, but in "name.nl" or "name.en" depending on the chosen locale on
the frontend.

My question is: is this the right way to handle localization?

Also, the highlighting doesn't work. I tried setting the highlighting
with the Java API as:

===
searchRequestBuilder.addHighlightedField("_source.name[en]");
searchRequestBuilder.addHighlightedField("name[en]");
searchRequestBuilder.addHighlightedField("name");
searchRequestBuilder.addHighlightedField("name.en");
searchRequestBuilder.addHighlightedField("_source.name.en");
searchRequestBuilder.setHighlighterPreTags("");
searchRequestBuilder.setHighlighterPostTags("");

And as you can see I have specified different combinations, but I
never receive the results surrounded by the 'b' tag. I know that the
field must be declared as stored in the mapping, and that is exactly
what I tried.

  1. I tried to setup "name" as stored, and then here's how my mapping
    looked like
    ===
    {"myproduct":{"properties":{"picture":{"type":"string"},"price":
    {"type":"string"},"description":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"name":
    {"store":"yes","type":"string"},"availableSizes":
    {"type":"string"},"en":{"type":"string"}}}}
    ===

  2. Then I tried to "name.en", and again the mapping:
    ===
    {"myproduct":{"properties":{"picture":{"type":"string"},"price":
    {"type":"string"},"description":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"name":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"availableSizes":{"type":"string"},"name.en":
    {"store":"yes","type":"string"},"brandName":{"type":"string"},"url":
    {"type":"string"},"pk":{"type":"string"},"availableColors":
    {"type":"string"}}}}

  3. The "name[en]", and here's the mapping:
    ===
    {"myproduct":{"properties":{"picture":{"type":"string"},"price":
    {"type":"string"},"description":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"name":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"availableSizes":{"type":"string"},"brandName":
    {"type":"string"},"url":{"type":"string"},"pk":
    {"type":"string"},"name[en]":
    {"store":"yes","type":"string"},"availableColors":{"type":"string"}}}}
    ===

  4. Last I tried setting only "en" as stored, and here's the mapping:
    ===
    {"myproduct":{"properties":{"picture":{"type":"string"},"price":
    {"type":"string"},"description":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"name":{"dynamic":"true","properties":{"en":
    {"type":"string"}}},"availableSizes":{"type":"string"},"en":
    {"store":"yes","type":"string"},"brandName":{"type":"string"},"url":
    {"type":"string"},"pk":{"type":"string"},"availableColors":
    {"type":"string"}}}}
    ===

After each of these I tried to search for something that gives result,
and I got no highlighting.

Does any of you have any idea how can I get a highlighting in my
search results?

Thank you for your time.
