2.11.9

🏆 Main features

Translation improved and added for German 🇩🇪 and Dutch 🇳🇱 !

As the Elasticsuite only consists of people of variable fluency in French and English, we have pretty much relied on the community for additional language translations.
A huge shout-out to @lewisvoncken who provided a huge contribution which not only improved and expanded the German translation but also added a brand new Dutch translation !
We'll try to get the ball rolling and address the gap between Elasticsuite Open Source and Elasticsuite Premium in that regard.

Changing your store language stemmer

Over the years, we've noticed some issues with the default language stemmers used in Elasticsuite where, sometimes, the stemmers would not recognize properly the plural form of a word (for instance irregular french plural or some legitimate italian plurals) or would provide the same stem for quite different words (collection and collectivité in french).

That led to the introduction of the stemmer_override analyzer step which allows a developer to add some stemming rules to address those issues.
But since another approach sometimes used by Elasticsuite end users was simply to test and switch to another available language stemmers, we've decided to make it possible from the Magento Admin.

In the Stores > Configuration, at the store view level, it will be now possible for you to select a different stemmer than the one Elasticsuite uses if ElasticSearch/OpenSearch provides several for your language, that is for: Dutch, English, Finish, French, Galician, German, Hungarian, Italian, Norwegian (Bokmal and Nynorsk), Portugueuse, Russian, Spanish and Swedish.

The configuration is available, at the store view level only, at Stores > Configuration > Elasticsuite > Analyzers settings > Language stemmer configuration (don't forget to perform a full re-index after changing the setting).

Slightly better UX on the indices grid

On a UAT or Staging environment where the Elasticsearch/OpenSearch cluster is shared by many Magento instances, it can be cumbersome to locate and inspect your live indices in the Elasticsuite > System > Indices grid if you have to scroll down 5 screens to reach them.
This release includes two small improvements

• the ability to filter indices by their name (and not only their alias)
• the ability to hide all the external indices
