Solr не может выполнить поиск записей, просканированных по принципу натч, несмотря на то, что поля подписаны как indexed = true

/ 02 апреля 2020

Я использую как экземпляр Nutch 1.16, так и Solr версии 8.3.0. Я смог сканировать файлы в локальном каталоге и, редактируя nutch-site.xml, извлечь из них некоторые метаданные (хотя и не так много, как я хотел), запустив bin/crawl -s urls dircrawl 2 >& dircrawl.log. Затем просканированные данные отправляются в Solr через bin/nutch index dircrawl/crawldb/ -linkdb dircrawl/linkdb/ -dir dircrawl/segments/ -filter -normalize, где записи затем сохраняются и управляются через их теги.

Теперь, запуская Solr Admin из пользовательского интерфейса, я пытаюсь найти данные. Я удостоверился, что подписал как indexed=true все записи, которые меня интересуют. ОДНАКО, выполнение любого поиска, кроме *:*, возвращает ноль результатов. Я перепробовал все возможные комбинации полей поиска, также ни одного кубика. Я сошлюсь на описание моих конфигурационных файлов, сначала для solr, затем для nutch ... 

schema.xml (becomes managed-schema when running it, for some reason)

Вы должны указать, в каком поле вы будете искать, если только у вас не настроено поле поиска по умолчанию . В более старых версиях схемы. xml это можно настроить для схемы, но рекомендуемый метод - настроить ее в самом запросе.

Однако для поддержки поиска в свободном тексте гораздо лучше использовать edismax парсер запросов, предоставив defType=edismax и затем указав, какие поля вы хотите искать с помощью параметра qf (поля запроса). 

q=Bumblebee&qf=title&defType=edismax

.. будет искать Шмеля в поле title. Вы также можете присвоить qf несколько имен полей, а также настроить веса, заданные для каждого из них: 

qf=title^10 content

.., который будет выполнять поиск как в title, так и content, и дать в десять раз больше вес всех попаданий в поле title по сравнению с попаданием в поле content.

Параметр fl (список полей) регулирует, какие поля возвращаются в ответе, что полезно, если вам нужно только небольшое подмножество доступных полей (например, только идентификатор), чтобы избежать большего отклика и необходимости загружать все значения полей с диска для каждого возвращаемого документа.

...
