Hello. Thanks for your nice words!
About searching in blog: our widget searchs inside .html files, and it seems your blog posts are not in .html format. Maybe you are using a widget from other provider? How do you create new posts there?
About removing partial string from page names: we did not test both widgets together, but our free Search and Replace widget maybe can do the job. You should place it in search results page and replace your sufix “- Scouting H. de Montfort – De leukste scoutinggroep van Hoensbroek” for a empty string (spacebar).
Tell us if it works!
