推荐答案
如果您进行前缀搜索，您将得到与前缀匹配的任何内容.
If you do a prefix search, you're going to get anything which matches the prefix.
如果您想要 IMDB id，就像您的其他问题一样，您可以搜索:
If you want IMDB ids, like your other question, you could search for:
ns:type.object.key "/authority/imdb/title
如果您想要所有电影类型的主题 ID，您可以搜索:
If you want all subject IDs of type film, you could search for:
rdf:type ns:film.film.$
换句话说，让您的搜索表达式与您要查找的内容相匹配.
In other words, make your search expression match what you're trying to find.
