Code

public function loadItems(array $ids) {

    // This method might receive two different types of item IDs depending on
    // where it is being called from. For example, when called from
    // search_api_index_specific_items(), it will receive multilingual IDs
    // (with language prefix, like "2/en"). On the other hand, when called from
    // a processor (for example from SearchApiHighlight::getFulltextFields()),
    // the IDs won't be multilingual (no language prefix), just standard
    // entity IDs instead. Therefore we need to account for both cases here.
    // Case 1 - language is in item ID.
