我想在包含“Opera”的字段“info”中找到。有没有人有想法？

Answer 1

db.collection.ensureIndex({ "$**": "text" })
db.collection.find( { 
                      $text: { 
                               $search: "Opera",
                               $caseSensitive: true
                             }
                    }
);

使用mongo中的文本索引
