I decided to start posting examples of where Search just doesn't handle the real world of my needs, in the hopes more examples may help Logos to improve it in the future.
In my study I recalled St. Paul saying "Christ became sin"....
I tried a Bible search with match all word forms: Christ became sin - no matches
I did a Bible search for: Christ sin. It found 40 verses, but nothing matching what I was looking for.
I tried "Became sin" (with quotes) - 1 match in OT.
So I went to Google, typed "Christ became sin" (with quotes), and voila- found it right away. 2 Cor 5:21 "For our sake he (God the Father) made him (Christ) to be sin who knew no sin, so that in him we might become the righteousness of God. "
