"X in N lines" is interesting because it's going to show you the minimal implementation of the interesting or central part of the solution without all the other moving parts of a production system, usually for the purpose of demonstrating how something works.
You can see how your 1-liner pitch doesn't fulfill this expectation.
You code just use an existing search engine and it would be 0 LOC, but I think you're missing the point. The focus wasn't on 80 LOC, but rather being able to talk through it in a short blog post.
I don't think that LOC affects one's ability to effectively communicate the way their code operates. And, if we really need to, lowering the amount of operations required to attain the desired result would be better than lowering lined of code, sine low ops = less explanation.
