when query by page, the page parameter doesn't works

my code will like this：
int page = 3;
int perPage = 10;
CosmosPageRequest pageRequest = new CosmosPageRequest(page, perPage, null, sort);
Page page = repository.queryXX(pageRequest);
But the page only return the first 10 records（1-10），not from 30 to 40。I had viewed the Code CosmosTemplate.java，found that the parameter page won't be used in any places。yours sincerely。
