Присвойте вес соответствующим полям

Question

Возникла проблема с Sphinxql. Я пытаюсь сопоставить несколько полей и дать каждому вес.

select id
       ,item
        ,param1
        ,param2
        ,module_id
        ,param2_id
        ,date_change
        ,custom_rank
        ,weight() as rank
        ,in(site, 336935152)
                        and if(date_from, date_from, 1578400079) <= 1578400079
                        and if(date_to, date_to, 1578400079) >= 1578400079
                        and ((((module_id = 3674251022)and(param1_id = 455881287)and(param2_id = 4196041389)))) as cond1
        ,if(date_to, date_to, 1578400079) date_to_nvl
        ,if(date_from, date_from, 1578400079) date_from_nvl
        from index
        where MATCH('@(title,body) (search query)')
        limit 0, 500
        option max_matches = 500
        ,field_weights=(title=99999, body=1)

Но вес не имеет значения. Даже если я присваиваю 99999 вес заголовку и 1 телу и наоборот, результат запроса не изменится. Моя цель - создать сфинкса, сначала сопоставить заголовок и после тела.

UPD: packedfactors() результат запроса

Answer 1

Используйте PACKEDFACTORS (), чтобы понять, что происходит, могут быть разные причины, по которым ваш рейтинг не меняется.

Ниже вы можете увидеть пример, который показывает, как его использовать, и, например, для некоторых статистика документов доступна только для одного поля из 2, потому что ключевые слова были найдены только в одном поле.
