历史
以以前的方法重建mongo结构以解决内存问题，前一种方法是按区域存储产品，并且所有值都是数组哈希（需要很长时间才能更新）。
当前问题
我似乎无法获取包含键“ x”和值“ y”的引用属性的产品。
聚合\生成器
这种方法只会给我局部值（一个产品可以在30个语言环境中包含5000个值），它的工作原理比Value文档中getValues（）上的repositoryMethod更快。
/**
* @param Builder $builder
* @param ExportFilters $exportFilters
*/
private function applyLocaleFilter(Builder &$builder, ExportFilters $exportFilters)
{
if (!$exportFilters->hasLocales()) {
return;
}
// reflectionClass lists properties (still want the name,created,etc with the results).
$fields = MongoProduct::getFieldNames();
// remove "values" key or else i get 5000 results instead of my filtered 90 results
$fields = array_diff($fields, ['values']);
$exp = $builder->expr()->eq('$$value.locale', $exportFilters->getLocale());
$builder
->project()
->includeFields($fields)
->field('values')
->filter('$values', 'value', $exp);
}
例如，我想使用相同的方法通过检查值和引用的属性来继续过滤值；
我希望所有与以下语句匹配的产品（语言环境的值：“ en_GB”）
值的引用属性应为（screen_size），且值必须为“ 16英寸”
它将返回所有与属性过滤与本地化值匹配的产品
