     ], 
     "articleName": "Ted Cruz, after trailing in polls, beats Donald Trump in Iowa caucus; Marco Rubio finishes a close third" 
    }

我有一個關鍵字列表的MongoDB中的文檔列表（如字符串[「王牌」，「唐納德」，「選舉」]），我想與這些文件中的keywords和articleName列匹配。

那麼，我怎樣才能得到匹配的文件集合使用$in or $or or regex在java spring-boot？

利用彈簧的數據！如果你想讓人們幫助你，請爲此表現出一些努力。 –

將你的'@ Repository'放在問題中，並且用這些信息實現的接口我們可以幫助你 – MaQuiNa1995

@Autowired 
private MongoTemplate mongoTemplate; 

Query query = new Query(); 
List<String> list = Arrays.asList("Trump", "Election"); 
query.addCriteria(Criteria.where("keywords").in(list)); 
List<YourModel> yourModel = mongoTemplate.find(query, YourModel.class);

我已經這樣做，通過使用正則表達式$以下實現：

BasicQuery query = new BasicQuery("{ keywords: { $regex: '(?:[\\s]|^)("+keywords+")(?=[\\s]|$)',$options: 'i' } } "); 
    articlesList = mongoTemplate.find(query, Articles.class);

其中的關鍵字是這樣的：關鍵字1 |關鍵字2 | KEYWORD3
