RediSearch PHP希望我在每次使用时定义所有字段

创建新的索引并在同一步骤中添加数据与seen in the docs相同.

但是，当我试图添加数据到现有的索引，我得到以下异常.

Ehann\RediSearch\Exception\FieldNotInSchemaException

The field is not a property in the index

以下是我的代码:

$adapter = new PredisAdapter();

$host = config('database.redis.default.host');
$port = config('database.redis.default.port');
$database = config('database.redis.default.database');
$password = config('database.redis.default.password');
$redis = $adapter->connect($host, $port, $database, $password);

$bookIndex = new Index($redis, 'books');

$bookIndex->add([
    new TextField('title', 'Tale of Two Cities'),
    new TextField('author', 'Charles Dickens'),
    new NumericField('price', 9.99),
    new NumericField('stock', 231),
]);

我研究了redisearch-php的源代码，似乎如果不总是添加带有addTextField或其他的字段，这是不可能实现的.但在我看来，这似乎不太现实.我想我必须在创建索引时添加一次字段.我说错了吗？

getFields方法(用于某些方法，如makeDocument)从Index获取对象变量，但如果事先未手动添加，则字段相关对象变量不在实例中.
