Dimension Filter LOV - Too many results; Refine your search

Hi,

I am using Dimension filter in Design Studio which uses the hierarchy dimension. In the preview mode the filter is not showing any members instead its asked to use the search functionality. I understand there is a limit in retrieving the LOV. Is anyway i can increase the number of LOV?

I need to have this functionality work, The user want to navigate the hierarchy in the filter. Please any help highly appreciated

Thanks
