java中的mongodb嵌套搜索查询

我对MongoDB搜索查询有疑问。我有两个参数，我必须搜索“文本”或“用户名”，还有更多的参数

因此，SQL查询如下所示：

select * from tbl where  place='pune' and (gender='male' or type='life') and (text='hi' or username='hi')

在MongoDB会怎么样

现在，我可以只使用一个参数进行搜索：

DBObject query = new BasicDBObject();
            BasicDBList dbl = new BasicDBList();

if (cmodel.getGender() != null) {

    if ("male".equals(cmodel.getGender().toLowerCase())) {
        dbl.add(new BasicDBObject(CrushModel.COLUMN_GENDER, "male"));
    } else if ("female".equals(cmodel.getGender().toLowerCase())) {
        dbl.add(new BasicDBObject(CrushModel.COLUMN_GENDER, "female"));
    } else {
        dbl.add(new BasicDBObject(CrushModel.COLUMN_TYPE, "crush"));
    }

    dbl.add(new BasicDBObject(CrushModel.COLUMN_TYPE, "life"));
    query.put("$or", dbl);
}

query.put("text", new BasicDBObject("$regex", String.format(".*((?i)%s).*", searchText)));
query.put(CrushModel.COLUMN_PLACE, new ObjectId(cmodel.getPlace().toString()));
DBCursor cursor = collection.find(query);



db.test.find( { $and : [  {gender : 'male' },
    { place :'pune'},{$or:[{text:/abc0/},{userName:/abc0/}, {type : 'life' }]}] } ) 

这不是我想要的方式

 there is one more field in table name "type" ,
for ex. if gender is male/female for which type is "normal" then i also want to show the type "life" here
    It is only showing me the either or result like the entries of all gender:male or only the entries of type "life", I want to show both of them.

它起作用了

db.test.find( { $and : [ { place : 'pune'},{$or:[{text:/hi u r looking awesome 10/},{userName:/hi u r looking awesome 10/}]},{$or:[{gender : 'male' },{type:'life'}]}] } )

谢谢@Disposer

mongo查询准确地说：

db.test.find(  { $and : [  { gender : 'male' }, { place : 'pune' },  { $or : [  { text : 'hi' }, { username : 'hi' } ] }  ] }  )

java将是：

ArrayList orList = new ArrayList();
ArrayList andList = new ArrayList();

orList.add(new BasicDBObject("text", "hi"));                  
orList.add(new BasicDBObject("username", "hi"));

andList.add(new BasicDBObject("gender", "male"));
andList.add(new BasicDBObject("place", "pune"));
andList.add(new BasicDBObject("$and", orList));

BasicDBObject query = new BasicDBObject("$or", andList);

使用MongoDB Java驱动程序v3.2.2实现上述操作的快捷方式。您可以这样做：

FindIterable<Document> iterable = collection.find(Document.parse("{$and: [{gender: 'male'}, {place: 'pune' }, {$or: [{text: 'hi'}, {username: 'hi'}]}]}"));

findierable iterable=collection.find（Document.parse（{$and:[{{gender:'male'}，{place:'pune'}，{$or:[{text:'hi'}，{username:'hi'}]}]）；

这将返回与上面相同的结果。

感谢您的回复。我想在查询中再添加一个参数，即type，例如。如果性别为男性/女性，类型为“normal”，那么我还想在这里显示类型“life”。我尝试用这种方式进行查询，但这并没有给出确切的结果。find（{$and:[{gender:'male'}，{place:'pune'}，{$or:[{text:/abc0/}，{userName:/abc0/}，{type:'life'}]}）。请帮助。它现在可以工作了。谢谢：）db.test.find（{$and:[{place:'pune'}，{$or:[{text:/hi-u-r looking awesome 10/}，{userName:/hi-u-r looking awesome 10/}，{$or:[{gender:'male'}，{type:'life'}]}）
