'decompoundedAttributes' => [ ['2-character country code' => ['attribute', 'attribute']], ['2-character country code' => ['attribute', 'attribute']], ... ]
About this parameter
Specify on which attributes in your index Algolia should apply word-splitting (“decompounding”).
A compound word refers to a word that is formed by combining smaller words without spacing. They are called noun phrases, or nominal groups, and they are particularly present in German. An example is Baumhaus, which is a contraction of Baum and Haus.
The goal of decompounding, regarding the previous example, is to index both Baum and Haus separately, instead of as a single word.
You can specify different attributes for each language.
As of today, the setting supports only three languages: Dutch (
nl), German (
de) and Finnish (
Note The attributes listed must have been defined by searchableAttributes.
Enable word decompounding for one language
In this example we consider an index having only one language (de) and where
we want to decompound only the attribute
1 2 3 4 5 6 7 $index->setSettings([ 'decompoundedAttributes' => [ 'de' => [ 'name' ] ] ]);
Enable word decompounding for several languages
In this example we consider an index containing two languages (de, fi) in different attributes
and where we want to decompound
description for both languages.
1 2 3 4 5 6 7 8 9 10 11 12 $index->setSettings([ 'decompoundedAttributes' => [ 'de' => [ 'name_de', 'description_de' ], 'fi' => [ 'name_fi', 'description_fi' ] ] ]);
