Eu tive que filtrar um tipo de conteúdo contendo as datas dos leilões em três grupos (agora on-line, disponível e pronto para se registrar). Como isso envolvia vários daterange, escrevi um plugin com base neste artigo: https://www.webomelette.com/creating-custom-views-filter-drupal-8
Basicamente, há três coisas: - Converta as datas no campo em data e hora local. - O filtro possui três configurações possíveis 'now online', 'coming' e 'other' - Com base nas configurações, ele adiciona as possíveis cláusulas where à consulta
Funciona e parece robusto para futuras atualizações.
