I'm observing odd Wikipedia results for certain search queries when it (Wikipedia) is pinned in domain personalization. For example, I've been directed to Llanfairpwllgwyngyll many times as the top search result for wholly unrelated queries. There's often no common text between the matched article and the search query, leaving me with very little understanding of why it's happening. It's possible I've observed this more with shorter (even single word) queries.
Steps to reproduce:
Pin en.wikipedia.org
in domain personalization settings (I suspect).
Expected behavior:
Return relevant results to search queries.
