Thanks for the suggestion, but I am more of a designer and less of a real developer. I tend to get lost in complex existing code like the PmWiki internal functions. I managed to fork Gilles' suggested cookbook recipe (SortByScore) and change it to suit my purpose for now. It's still some kind of a quick and dirty solution as SortByScore uses fmt=score with a fixed SDV instead of order=score with the option to use your own fmt templates from Site/LocalTemplates.
• does the job somehow
• configureable weight multiplier for title
• leightweight cookbook recipe solution
• extends already existing (:pagelist:) functionality
• lacking visual customization (uses fixed fmt=score instead of order=score)
• no normalization of score (for consistent gui visualization of search result quality, e. g. always 5 stars for top result/s)
