This is mentioned in English, but it seems it would be true in other languages, too.
Lord refers to Adonay in Hebrew; LORD refers to Yahweh in Hebrew when done in the NIV.
Yahweh is rendered in the text as \nd Lord\nd* It shows in the text either with those markers or with the markup that differentiates it.
Now, move over to Biblical Terms. A search for Yahweh shows this text as "Lord" and there are no \nd markers. A person taking a cue from those visual markers (seeing \nd or seeing LORD) is NOT helped.by this. How can I have, for example, the NIV as a comparative text and see visually "LORD" instead of "Lord" or "\nd Lord\nd* instead of Lord?
