Petscan and Wikidata Queries

Advanced searches
editIn the Special:Search bar, you can write down:
-insource:"<ref>" deepcat:Name_of_the_Category
-insource:"<ref>"
stands for: without (hence the minus sign) the references' template (<ref>)
deepcat:Name_of_the_Category
"deepcat" means you're looking for articles inside this category but also subcategories.

editArtículos de Colombianas Sin Referencias

editPersonnes de la catégorie "Personnalité féminine camerounaise" sans références
⚠️ Veuillez noter que la sous-catégorie "Sportive camerounaise", a une sous-catégorie "Wikipédia:ébauche sportive camerounais" qui n'est pas séparée par genre (car elle inclut "Wikipédia:ébauche_footballeur_camerounais") c'est pourquoi beaucoup d'hommes apparaîtront également.
