Hereness (doykayt) was a movement related to the Jewish Labor Bund from the 1920s which disagreed with Zionist Jews about the best way to secure a future for Jews in Europe. The actual first result of the search does a decent job summarizing it: https://haam.org/the-bund-hereness-and-resistance/
The problem I'm reporting is the Wikipedia card shows "Heresy in Judaism". That's not relevant to the topic of hereness, since hereness isn't about religious beliefs.
The rest of the search results page is fine and so I suspect this must just be a bug related to these wikipedia cards. A search on Wikipedia for "jewish hereness" does not make this mistake (https://en.wikipedia.org/w/index.php?search=jewish+hereness&title=Special:Search&profile=advanced&fulltext=1&ns0=1)
It's a funny bug, but a bug nonetheless.
The wikipedia widget should either be absent, because the topic has no dedicated Wikipedia page. Or it should be for the Bundism Wikipedia page, since these are nested topics.
