Elasticsearch 用于不确定量 i18n

Question

I am using elasticsearch-php in a laravel project.

I have a products table like below

CREATE TABLE `products` (
    `id` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
    `title` JSON NOT NULL,
);

The title of each product will have multiple languages, and the type of language is uncertain

+------------+---------------------------------------------------------------------------+
|     id     |                                   title                                   |
+------------+---------------------------------------------------------------------------+
|      1     |{"en-US":"Toyota Cruiser","ja-JP":"トヨタクルーザー","zh-CN":"丰田酷路泽"}    |
+------------+---------------------------------------------------------------------------+
|      2     |{"en-US":"Subaru Outback","ja-JP":"スバルアウトバック"}                      |
+------------+---------------------------------------------------------------------------+
|      3     |{"zh-CN":"路虎 揽胜","ja-JP":"ランドローバーレンジローバー"}                   |
+------------+---------------------------------------------------------------------------+
|      4     |{"en-US":"BMW X5"}                                                         |
+------------+---------------------------------------------------------------------------+

How can I create a elasticsearch index for products table which supports search in i18n?

Thanks a lot!

Answer 1

I can see you have the language identifier in your database as en-us , zh-cn which means before storing the title, you know the language of product, than you can simply use the multi-field and can add a new language sub-field for all the available languages in Elasticsearch.

You can have a look at all the current supported languages in Elasticsearch and add all the sub-fields in beginning or change the mapping and add a new language sub-field as you get it in your system.
