I have found that searches revision would be much more agile and useful if Okular included, after entering the search term, an additional tab in the left panel (next to the tabs where the thumbnails, annotations and bookmarks appear) showing a line for each place where the term has been found (with the text adjacent to the search term) and that you can click on these lines to quickly access the page where the search term has been found. This is not a new idea, it is done by Abby Fine Reader and it is very practical and productive. Best regards
