How to set match mode to SPH_MATCH_EXTENDED2 ?

[marios88]

Hello i am in the process of migrating to manticore from an old sphinx installation but i cannot find any options on how to set match mode to SPH_MATCH_EXTENDED2, is it not supported?

Here is part of the old code for reference

    $sphinx = new SphinxClient;
    $sphinx->SetServer('localhost', 9312);
    $sphinx->SetMatchMode(SPH_MATCH_EXTENDED2);
    $sphinx->SetRankingMode(SPH_RANK_EXPR,'sum((4*lcs+2*(min_hit_pos==1)+exact_hit)*user_weight)*1000 + IF(IN(f1, "1"), 0, 10000) + IF(IN(f2, "1"), 0, 10000) + bm25');
    $sphinx->SetFieldWeights(['email' => 0]);
    $sphinx->Query($s, 'index0')['matches'];

SPH_MATCH_EXTENDED2 was temporary even in Sphinx. It's not supported in Manticore, at least officially (nothing about it in the docs https://manual.manticoresearch.com/)

You can use option() to specify search options including ranking options. See https://github.com/manticoresoftware/manticoresearch-php/blob/master/docs/searchclass.md#option

Thank you @sanikolaev for helpful insight and quick reply.

For anyone interested here is my current code for emulating the old SPH_MATCH_EXTENDED2 match mode used in an autocomplete system

$search_string = 'ragon fire'; // needs to match "dragon fireplace"
$search = implode(' ',array_map(static function($v){
    return '*'.$v.'*';
},explode(' ',preg_replace('/\s+/', ' ', $search)))); // expanded to "*ragon* *fire*"
$manticore->match(self::escape($search))->get();
