Random observation: When I use the search function to search for posts by myself with the keyword "revision", I get a list of six purported matches that actually do not contain the keyword, and the posts' content remains completely hidden in the search result.
Searching for my own posts that mention "kartoffelsalat" returns an empty list of matches (which is likely correct up to the moment I submit this post).
Searching my posts for "edition" displays many matches (including those with "expedition"), which is to say that a snippet of their content is shown, with the keyword highlighted.
... I suppose that the first result is not quite as it should be?
