SPARQL查询:还是在过滤器中？

Question

我想根据案件的简短标题搜索法院案件，但我在RDF记录中注意到，这些信息有时存储在一个属性(cdm:expression_law_parties)下，有时存储在另一个属性(cdm:expression_title_alternative)下。我想同时对两者进行过滤。下面的查询(我试图在过滤器中使用OR || )不起作用。什么是合适的方法？

PREFIX cdm: <http://publications.europa.eu/ontology/cdm#>
                            SELECT ?work ?expression ?ecli ?celex ?alttitle ?parties ?title
                            WHERE {
                            ?work a ?class.
                            ?expression cdm:expression_belongs_to_work ?work.
                                ?expression cdm:expression_title ?title.
                                ?expression cdm:expression_uses_language <http://publications.europa.eu/resource/authority/language/ENG>.
                            ?work cdm:case-law_ecli ?ecli.
                            ?work cdm:resource_legal_id_celex ?celex.
                            OPTIONAL{?expression cdm:expression_case-law_parties ?parties}
                            OPTIONAL{?expression cdm:expression_title_alternative ?alttitle}
                            FILTER(?class in (<http://publications.europa.eu/ontology/cdm#judgement>))
                            FILTER CONTAINS (?alttitle, "France v Commission") || (?parties, "France v Commission")}

LIMIT 15

来自Stanislav Kralin's comment

FILTER (CONTAINS (?alttitle, "France v Commission") || CONTAINS(?parties, "France v Commission"))
