Error on JSON decode after keywords request ("\x03" symbol)

[DenisAlliswell]

Hello! First of all, thanks for the awesome tool and great job to all of the Manticoresearch team !

Below's my index settings:

$index->create([
    'db_id' => ['type' => 'int'],
    'name_full' => ['type' => 'text'],
], [
    'morphology' => '',
    'bigram_index' => 'all',
    'min_infix_len' => 2,
    'index_exact_words' => 1,
    'expand_keywords' => 1,
]);

$id = 1;
$name_full = "Some long product name...";

$index->addDocument([
    'db_id' => (int) $id,
    'name_full' => (string) $name_full,
]);

$keywords = $client->keywords([
    'index' => $indexName,
    'body' => [
        'query' => "$term*",
        'options' => ['stats' => 1, 'sort_mode' => "'hits'"]
    ]
]);

After request on keywords I got this error:

Manticoresearch\Exceptions\RuntimeException: fatal error while trying to decode JSON response in /app/vendor/manticoresoftware/manticoresearch-php/src/Manticoresearch/Response.php:76

Here's the raw response result:

It seems that issue is related to "\x03" symbol. For some reason, Manticore puts it instead of whitespace.

[tomatolog]

seems daemon passes keyword from dictionary as is into HTTP reply however fixes up keyword when passes it into API and SphinxQL

Should be fixed at Manticore searchd binary but not at this library

The root cause is manticoresoftware/manticoresearch#788. As soon as that's fixed this issue should be gone too, so I'm closing this one.
