How to add 200+ issues to a test plan?

I have created a test plan. I want ao add all the Jira issue tickets which was slated for a release to this test plan, which comes to around 250 issue.

When I use the Advanced search and select a filter to show all the 250 issues from 'Add existing issues' - in total only 40 issues are showing up to be selected.

There is no next button or anything else to traverse through the remaining issues from the filter.
