How to find an Object by attribute value

HI ,
I'd like to search an object by the value of Attribute ID 101227.do we have a High efficiency way to find this object or I have to find all objects then use linq to filter it ?

 private List<ObjectItem>  GetallChildren(ObjectItem item,int type=-1 )

        {

            ObjectDataRequest request = new ObjectDataRequest();

            List<ObjectKindInfo> funckind = new List<ObjectKindInfo>() { new ObjectKindInfo() { CoverId = 123 } };

            request.StartObjectId = item.ObjectId;

            request.OutputObjectKindList = funckind;

            request.SearchMode = SearchMode.Flat;

            request.OutputDesignation = true;

            if (type!=-1)

            {

                request.OutputAttributeList = new List<AttributeInfo>() { new AttributeInfo() { AttributeId = Comm.gs_Attr_TypeID } };

            }            

            ObjectDataResponse respon = _proxy.GetObjectData(_databaseName, request);

            return respon.ObjectData.ToList();

        }

I use this to get all children then compare the value one by one.
