can't use option “field_weights”

[jShi-git]

vendor/manticoresoftware/manticoresearch-php/src/Manticoresearch/Transport/Http.php 中,第 147 行] ："unknown option 'field_weights'"

$results = $index->search("@(title,description) ".$words)
                ->sort("_score", "desc")
                ->sort('updatetime','desc')
                ->option("ranker", "sph04")
                ->option("field_weights","(title=20,description=1)")
                ->limit(10)
                ->get();

in mysql, it's ok.

mysql> SELECT id, title FROM wenku WHERE match('ok') limit 3 OPTION ranker=sph04,field_weights=(title=10, description=3);
