Full Text Search GetSearchResults Only Allow Page Less Than 100

I am doing a pagination for results from a full text search. The search function I am using is:

SearchHandler.GetSearchResults(IQueryExpression queryExpression, int page, int pageSize)

I did a search witch returns 2000 results, and my page size is 10, so the total page number should be 200. However it starts to return empty search result when the page parameter passed in is larger than 100.

I doubt the users will go to pages that far, but it still makes the site appear broken. What should I do to get around the hidden page limit?
