query GetArticleInSpanish {
  article(codename: "about_us", languageFilter: {languageCodename: "es-ES"}) {
    title
    # other elements
  }
}

# Filters all articles to find the Spanish variant by its URL slug
query GetArticlesByLocalizedSlug {
  article_All(where: {title: {eq: "acerda-de-nosotros"}}, languageFilter: {languageCodename: "es-ES"}) {
    items {
      title
      # other elements

# Gets content items in Spanish without following language fallbacks
query GetArticlesInSpanishOnly {
  article_All(
    # Requests items in Spanish
    languageFilter: {languageCodename: "es-ES"}, 
    # Filters the items so that only Spanish is returned
    where: {_system_: {language: {_system_: {codename: {eq: "es-ES"}}}}}) {
    items {
      title
      # other elements
