It makes no sense to me that the Clause search won't search the whole Bible. I appreciate that lemma searching is language-specific, but the rest of the syntax isn't language specific, and therefore isn't OT/NT specific. Besides, the presence of Swete means even lemma searching can be carried out across the OT/NT.
Here's on example of a search that would be useful across the entire Bible (there are hundreds of other examples): subject:god verb-sense:to love (care)
I suggest that the tool adds a few collections to the current choices of LHB/Swete/SBLGNT:
- Original languages (LHB, SBLGNT)
- Greek OT and NT (Swete, SBLGNT)
- All resources (LHB, Swete, SBLGNT)
If this was added, then the addition of the Grid view, would add even more functionality, including the ability to easily compare clause searches between the Hebrew Bible and LXX.
