Fuzzy search and conflated verses

When/if you ever re-implement fuzzy search, here's something I'd want it to be able to help me with.
A verse came to my mind, and how I remembered it was something like "they that walked in the valley of the shadow of death, upon them hath the light shined"
The verse I was thinking of was of course Isa 9:2, but I had conflated it with Ps 23:4.
I tried to find it in Logos by typing walked valley shadow into a Bible search in my Search Bibles collection (which is all the English Bibles that I ever use, 21 of them in all), and it came up with zip. Of course that's the "right" answer because those words don't ever appear in the same verse. But I would want Logos to be able to sort out my fuzzy memory for me and point out both of those verses I had conflated as possibilities for what I had in mind. Then I could look at the options and see that it was Isa 9:2.
Note that I was able to type part of my misremembered quote into Google and find exactly what I was looking for. Apparently I'm not the only one who has misremembered that verse, but the others have remembered the citation, and that was all I needed:
