I am trying to determine why I get different search results on the Nestle-Aland (NA28) and United Bible Societies (UBS5) Greek New Testaments. Both have the same Greek text, but minor differences in punctuation.
For example, a Morphological search in the book of Titus for @N BEFORE 1 WORDS lemma:καί produces the following differences:
- In Titus 2:13, a search in NA28 finds ἐλπίδα καὶ and θεοῦ καὶ, both of which are correct. But the same search in UBS5 only finds ἐλπίδα καὶ in this verse. The only difference is that UBS5 has a superscript "g" for a footnote after θεοῦ.
- In Titus 3:8, the search in NA28 finds λόγος· καὶ, but the search in UBS5 does not find this verse. In this case, the NA28 has a stop (a raised dot) as well as an asterisk for a footnote. The search quite properly ignores the punctuation and superscript symbol. But the same search on UBS5 does not consider this a match, evidently due to the superscript "c" for a footnote.
I have the same problem if I search for the phrase "θεοῦ καὶ". The search in NA28 finds Titus 1:1 and 2:13, but the UBS5 only finds Titus 1:1. The phrase search seems to be thrown off by the superscript.
I have never noticed in other resources that a search is thrown off by a superscript for a footnote. Logos always ignores footnote numbers and letters in English Bibles and it ignores the many types of footnote symbols in NA28. But searches in the UBS5 act like the superscript footnote symbol is a separate word.
Here is proof that the footnote symbol is being treated like a word in a search in UBS5. Here are 2 searches in UBS5, which has the phrase θεοῦ καὶ in Titus 2:13.
- Search for θεοῦ BEFORE 1 WORD καὶ does not find Titus 2:13.
- Search for θεοῦ BEFORE 2 WORDS καὶ does find Titus 2:13.
Since θεοῦ καὶ are adjacent, I would expect a search for θεοῦ BEFORE 1 WORD καὶ to find this verse as should a phrase search "θεοῦ καὶ". But Titus 2:13 has a superscript footnote symbol after θεοῦ, which the search apparently treats like a "word". The same search in NA28 finds this verse.
In my mind this is a pretty significant bug or at the least unexpected behavior. Nowhere else in Logos is a superscript number or letter treated like a "word".
