SEARCH functionality

The SEARCH is nice but it SHOULD HAVE some options.
The most evident one is that we want to limit the search to the BIBLE BOOKS ONLY (sub choice OT only, NT only, whole BIBLE). (do NOT include the notes)
We are first of all studying the Word of God itself and not all accompanying books.
Maybe an other option should be to limit the SEARCH to the notes and then to all other books or even better to the MAIN DIVISION in GROUPS and SUBGROUPS …
But the most significant one to me, is to search BIBLE BOOKS ONLY.
This request is more or less a duplicate, but wondering if this can be implemented in the near future?
