Revert "Merge branch '1047' into 'main'"

Related to !1943 (merged)

It seems that this MR broke the search results page. You can search from the landing page, and get results in the dropdown, but the results page itself (if you click through) is blank.

@mkaeppler got this error: Uncaught (in promise) TypeError: hit._highlightResult.hierarchy.lvl1 is undefined, so it does seem related.
