Solr Результаты поиска всегда равны 0 .0

Question

Мы пытаемся оценить Solr как решение для поиска и столкнуться с проблемами при поиске баллов. Мы сканировали и индексировали, но все баллы приходят как 0.0, несмотря на то, что мы не изменили какую-либо конфигурацию в отношении оценки по нашим знаниям.

Было бы здорово, если бы кто-нибудь мог реплицировать и сообщить нам причину здесь. Было бы большой помощью.

Solr версии 4,2

Answer 3

Я имел www.mcdonalds.ca домен configurd в моем фильтре. Поскольку это перенаправлялось на www.mcdonalds.ca.ca/en.html, оценка не поступала ни по одному из URL.

Я изменил верхний URL-адрес, а вместо www.mcdonalds.ca я упомянул www.mcdonalds.ca/ca/en.html, и это сработало.
