[Help] не работает поиск после импорта из csv.

[Sanya]

Здравствуйте, Уважаемые!

Столкнулся с такой проблемой:
после импорта товара из .csv не работает поиск сайта, т.е. эти товары через поиск не находятся...
Товары, добавленные руками - находятся, проверял.

В чем может быть проблема, было ли такое у кого нибудь и как можно победить все это.

Спасибо!

[Sanya]

Никто не знает что ли???? ((

[Your Friend]

Не знает. Остальным лень.

как давно я тут не был!
если еще надо, возьмите файл Search.php, прикрепленный к этому посту, залейте в папку /classes
после этого надо пересоздать индекс из админки.
проблема в том, что в престе традиционно под названия выделяется мало места, в том числе в версии 1.3 длина поля всего 128.
а вообще, ищите ответу у шопмастера - http://shopmaster.blogmasters.ru

Search.php

Столкнулся с такой-же проблемой. Делаю импорт через Store Manager. Частично помогает пересоздание индекса в Store Manager, но описания все равно не индексируются. Есть решения?

[Kerm]

В админке престашопа на вкладке поиск тоже есть индексация..

[absent]

Пересоздать индекс в настройки--поиск!!

[ali3412]

Забыл уточнить. Пересоздание индекса из админки работает только на те товары которые были открыты или с сайта или из админки.

То есть у меня после импорта такая картина с индексом товаров: Проиндексированные товары: 0 / 46038

Если нажать на переиндексацию или "добавить потерянные товары в индекс" то будет так же "0 / 46038"

Но если открыть на сайте карточку товара или в админке, то переиндексация даст такой эффект "1 / 46038"

Кэш не помогает

 

Кажется решил проблему, убрав галочку с "переиндексировать все товары" при импорте в Store Manager. Хотя не понимаю почему, ведь до импорта описание товаров не было добавлено в индекс, а сейчас все норм.

[absent]

покажите строку из файла импорта

[ali3412]

Название продукта ; Цена ; Количество ; Краткое описание ; Категория ; Статус ; Описание ; Изображения продуктов

Браслет Love 560819 Выбражулька ; 10,74 ; 0;0 ; 47431 ; Главная | *НОВИНКИ**ПОДАРКИ ПРАЗДНИЧНЫЕ | БИЖУТЕРИЯ | БИЖУТЕРИЯ детская ; 0 ; Код: 47431<br />В пачке: шт ; 47431.jpg

 

 

Ещё обратил внимание что Store Manager при импорте не заканчивает генерацию картинок и удаляет исходник, из-за чего из админки потом тоже не сгенерировать изображения.

Не уверен, но кажется проблема была в том что разделитель картинок стоял такой-же как и разделитель значений. В посте выше я не указал, но после столбца картинок у меня ещё столбец есть который я не включаю в импорт.

Разделители везде одинаковы!

разные только для полей и значений.

[ali3412]

Мда,.. смена разделителя не помогла. Менеджер до сих пор не импортирует львиную долю картинок

[absent]

какие ошибки пишет?

[ali3412]

С картинками разобрался. Но индексация все-равно страдает: часть товаров не находится поиском, в админке пишет что все проиндексированны. Пересоздание индекса через админку удаляет весь индекс, не добавляя новый (в итоге 0/9999). Пересоздание индекса через SM не дает результата.

[Kerm]

Какая версия престашопа? с индексированием после импорта через SM не у одного у тебя такая проблема, ищи поиском похожие темы в гугле, может в них есть ответ.

 

 

Как вариант еще, попробуй mysql базу проверить, сделай проверку, анализ, оптимизацию, попробуй после заново пересоздать индекс...

 

Может ты до этого когда разбирался с импортом криво какой то товар импортировал и нарушил структуру mysql базы, попробуй удалить все товары и заново импортировать..

[randvell]

У меня тоже проблема с индексом. Но проблема в другом. Индексируются ТОЛЬКО английские слова и индексы.

 

 

Замена d800 на e000 не помогла

 

Prestashop 1.4.4

Edited July 29, 2013 by randvell (see edit history)

[Kerm]

С твоей версией престашопа даже говорить не о чем и не кто разбираться не будет, обновляй на более свежую версию, хотя бы на 1.4.9.1

[ali3412]

Нашел решение для себя тут

[vipvizitka]

Мне тоже не помогло залил с другого сайта файл search.php - помогло. Вот его код:

I Prestashop Version 1.6.1.1

After you import the ssv stopped working search in Russian.

Apple hammered - finds both English and Russian version (apple and "яблоко")

If you drive in the "яблоко" - he finds nothing.

After you install the search worked correctly .... Where to look?
