suggest не работает

```
$config = ['host'=>'manticore','port'=>9308]
$client = new Client($config);
$suggest = $client->index('suggest');
$suggest->create([
'explanation' => [
'type' => 'text',
],
],
[
'min_infix_len' => 1,
'dict' => 'keywords',
]);

$suggest->addDocument([
'explanation' => 'Автобус',
]);
```

затем:

```
$query = [
'index' => 'suggest',
'body' => [
'query' => 'овтобус',
'options' => [
'limit' => 1,
],
],
];

$r = $client->suggest($query);
```

No source files or tests are named. Start by reproducing the PHP create, addDocument, and suggest calls from the issue, then trace the client's suggest implementation and existing search-related tests. Done means determining why the typo query returns no result and adding a verified fix or a clear documented limitation.
