The search dialogs (as used for searches, but also e.g. for showing more "other versions") currently don't show results beyond the query limit, which is 50 by default but can be increased to up to 100 in the options.

100 is a hard server side limit, so the dialog will never show more.

Ideally the dialog should use the pagination mechanism of the web service to load more results when needed. This could e.g. happen on scrolling.
