Wikicite created many Wikidata items and that's great but sometimes that makes searching hard. If I type "heart rhythm" in the newly proposed search engine it doesn't manage to list the correct item at the top.
There are similar concerns for other bot created articles in geology, musical songs and films.
I think a good solution would be to store the amount of human edits that each item gets as a variable that's meaningful for the search ranking. Items about scientific articles that don't have any human edit should be downranked as a result.
