At the end there are three points that suggest more results are to be found but clicking that shows nothing.
Actually this limit of 10 is hard-coded in the software code of
libwidgets/View/SearchResults.vala, lines 59-61)
const int MAX_RESULTS = 10; const int MAX_DEPTH = 5; const int DELAY_ADDING_RESULTS = 150;
You can even increase this number in order to display more results, but nevertheless the number of results displayed stays limited. You can change the number 10 after
MAX_RESULTS = to the value wanted in the file and rebuild the package (
debuild -us -uc).
So you still might want to file a feature request to implement a way of showing all results when you click on the "…", however.
