Champs
el_id
| Version de MediaWiki : | ≥ 1.22 |
Clé primaire. Actuellement ne sert à rien, mais sera utile lors des modifications en ligne du schéma.
el_from
L' ID de la page qui référence la page wiki.
el_to_domain_index
| Version de MediaWiki : | ≥ 1.40 |
Ceci est similaire à el_index mais inversement inclut uniquement la spécification du protocole et le domaine, de sorte que http://en.wikipedia.org devient http://org.wikipedia.en..
el_to_path
| Version de MediaWiki : | ≥ 1.40 |
Uniquement le chemin de el_to.
Exemple :
/wiki/Main_Page
el_to
| Versions de MediaWiki : | 1.6 – 1.41 Gerrit change 954900 |
L'URL actuelle elle même. Elle est passée au navigateur.
el_index
| Versions de MediaWiki : | 1.6 – 1.41 Gerrit change 954900 |
C'est la même URL que el_to optimisée pour la recherche : les informations relatives au nom d'utilisateur et le mot de passe sont enlevées et les autres composants sont inversés pour accélérer la recherche, donc http://user:password@sub.example.com/page.html devient http://com.example.sub./page.html, qui permet les recherches de la forme 'Afficher tous les liens pointant vers *.example.com'.
el_index_60
| Versions de MediaWiki : | 1.29 – 1.41 Gerrit change 954900 |
Ceci équivaut à el_index tonqué à 60 octets, pour permettre les requêtes de tri non prises en charge par l'indexation partielle.
