Hi Ernest, thank you very much for pointing that out. I made a new Search Results page in Elementor Theme Builder and now it seems to work as expected: both ways to search give the same good results.
One little thing though is that in the search results every text below the post title (that is on a page, not a blogpost) starts with the words ‘Opleiders Kandidaten Werkgevers Opleiders Kandidaten Werkgevers’ because that is what is being used as navigation on almost every page and is the first content on the page.
Is there a way to get rid of that in the results text (excerpt)?
