By default, the search ignores German umlauts. Searching for “uber” will also find “über” and so on. This ignorance is not a Relevanssi feature but instead governed by your database. The default database collation WordPress uses (utf8mb4_unicode_ci) ignores all accents, including umlauts. If you want the search to care about umlauts, you can change the…

All that meaningful punctuation and single digits make exact matching of Bible verses really difficult for Relevanssi, and when searching for Bible verses, exact results are what matters – hitting something similar is generally not very helpful.
