It is a bug and a suggestion at the same time.
1. I opened a commentary, specifically, Pillar New Testament Commentary: The Gospel accroding to John.
2. I entered john 4:14 to look up the contents for verse John 4:14, obviously.
3. But the text box interprets that string into "John 4:1–42"...and the content goes to the top of chapter 4.
4. I can see why it does... 4:14 matched to 4:1-4 somehow... and the commentary has index for 4:1-42, and even though the contents is devided into many verse groups. it has a block for 4:13-14, but this block is not listed in the index.
5. But it would be great if I enter John 4:14, it goes to the section of 4:13-14 instead of the start of chapter 4!
