1. 确保您的API Platform版本高于2.5.0，并且在entity中使用了@Property（array = true）注释。

2. 为API Platform添加自定义的过滤器，以便在关系列上正确执行搜索。例如，您可以使用以下代码示例中的自定义Filter类：

// src/Filter/RelatedSearchFilter.php
getProperties($resourceClass);
        $attributeName = array_search($association, $associations);
        if (!$attributeName || !isset($associations[$attributeName]['search'])) {
            return;
        }
        // Specify an alias to prevent collisions in the search query.
        $alias = 'o_' . str_replace('.', '_', $association);
        // Create the join query.
        $rootAlias = $queryBuilder->getRootAliases()[0];
        $queryBuilder->leftJoin(sprintf('%s.%s', $rootAlias, $association), $alias);
        // Filter the query based on the searchable property.
        $property = sprintf('%s.%s', $alias, $assocProperty);
        $this->addWhere($queryBuilder, $property, $value, $alias, $associations[$attributeName]);
    }

    public function getDescription(string $resourceClass): array
    {
        $description = [];
        $properties = $this->getProperties($resourceClass);
        foreach ($properties as $property => $info) {
            if (!$info || !isset($info['search'])) {
