在jsp中實現mongodb文本搜索

我想在jsp頁面中實現mongodb文本搜索，但出現錯誤。以下是我的代碼和錯誤。如果您發現代碼有問題，請告訴我。我們非常感謝您的幫助。提前致謝。在jsp中實現mongodb文本搜索

代碼：

Mongo m=new MongoClient("localhost",27017); 
DB db = m.getDB("sagar"); 
String searchText="samosa"; 
DBCollection collection=db.getCollection("review"); 
DBObject searchCmd = new BasicDBObject(); 
searchCmd.put("text",collection); 
searchCmd.put("search",searchText); 

DBCursor cursor = collection.find(searchCmd); 

while(cursor.hasNext()) 
{ 
    System.out.println(cursor.next()); 
}

錯誤：

正試圖地圖集合對象，以價值與重要文本：

searchCmd.put（「文字」，收藏）

您可能只需要執行searchCmd.put（「search」，searchText）; （{「search」：「samosa」}）
