Replicas

Replicas can be created with the replicas function on IndexSettings. To configure replicas, include them in the indices array and set their replicaIndex to true so that they are not included in any syncing operations.

Replica indices can have their configuration updated using the ./craft scout/settings/update console command.

return [
    'indices' => [
        \rias\scout\ScoutIndex::create('Products')
            // ...
            ->indexSettings(
                \rias\scout\IndexSettings::create()
                    ->minWordSizefor1Typo(4)
                    ->replicas(['virtual(Products_desc)'])
            )
    ],
    [
        \rias\scout\ScoutIndex::create('Products_desc')
            ->replicaIndex(true)
            ->indexSettings(IndexSettings::create()->customRanking(['desc(price)'])),
    ],
