Filter list of Object in Rxjava

I want to filter List<Object> based on query from user and then return List<Object> to him/her.I found out how to filter items But the problem is I don't know how return List<Object>. I also see some approach which iterate and call flatMap each time But I didn't think it's an elegant way.

This is my last attempt:

      Observable.from(my_list_of_object)
                    .debounce(500, TimeUnit.MILLISECONDS)
                    .filter(new Func1<MyObject, Boolean>() {
                        @Override
                        public Boolean call(MyObject o) {
                            return o.getName().contains(query); //filtering
                        }
                    })
                    .observeOn(Schedulers.computation())

                   //problem is here and I dont know how 
                   //to convert filtered Item to list

Just use toList() operator. Check the documentation.

      Observable.from(my_list_of_object)
                    .debounce(500, TimeUnit.MILLISECONDS)
                    .filter(new Func1<MyObject, Boolean>() {
                        @Override
                        public Boolean call(MyObject o) {
                            return o.getName().contains(query); //filtering
                        }
                    })
                    .toList()
                    .observeOn(Schedulers.computation())

You can find more extensive list of aggregate operators here.
