I'm just curious. When searching for "Lord Jesus" but not "Lord Jesus Christ" in the Pauline corpus, I tried:
"Lord Jesus" NOT THEN Christ
and
"Lord Jesus" THEN NOT Christ
Neither of those worked. However, the following worked:
"Lord Jesus" NOT BEFORE Christ (although this leaves out 2 Thes 1:12 which has a positive search result but also has Christ later in the verse)
"Lord Jesus" NOT WITHIN 1 WORD Christ (this gives the best results)
Question: Why can't I use NOT in conjunction with the THEN operator when I don't want a term to immediately follow another term but it can be somewhere else in the verse?
