Odd search result

I'm trying without success to figure out why, when I search the database for “burst ye emerald gates and bring”, in addition to the hymn I was looking for a second result came up: https://hymnary.org/hymn/HBCH1840/page/331 - I can see no good reason (nor even a bad one) that would account for this. If it is somehow connected with my search, I'd like to know how. If it's not, I wonder if there's a good way to block its appearance in this situation.
