How to configure sphinx search so that word order is not taken into account?

Question

Sphinx

Here is the index config:

index catalog
{
source = catalog
path = /path

morphology = stem_enru

min_word_len = 1
min_prefix_len = 0
min_infix_len = 2
enable_star = 1
expand_keywords = 1
}

There are results for the query "white gold", if you change the order of the words "gold white" - there are no results.

using yii2

$rows = $query->from('catalog')
            ->match(new MatchExpression(':match', [
                'match' => $q,
            ]))
            ->all();

Answer 1

The problem was not in the settings of the sphinx, but in the request itself. If the string is wrapped in a MatchExpression, then in the sql query it turns out like this: If you do not use MatchExpression, then the query does not contain brackets, and the search works as it should.
WHERE MATCH('\"Search str\"')
