I'll own that I could see why you might think that I think a certain way but consider that we do not disagree? I pointed out that - with a premium on billing efficiency - the linchpin the product's actually delivering value in such an environment would still rely on (what I note as) _the assumption that_ a semantic+graph -based product does in fact cut down research hours, compared to the boolean-based approach.
Your explanation about the value of exceptions to rules in research is correct and would occur to, say, pretty much anyone who has drafted a motion (worth clarifying: not a drag on you). Far from a disagreement, the truth of this premise is why - as I pointed out - the most experienced/valued appellate drafters effectively rely on boolean. (Except, I guess, the 'within' operator might count as a semantic operator. Although that's been in lexis and west for as long as I've seen them, and I suspect have found immense use for much longer than that...)
edit: Adding that of course only one of the two following premises need be incorrect (firms should use products which enable them to spend less time on research; the citation graph enables lawyers to spend less time on research while yielding identical quality; firms should use citation graph -based products). Depending on your circumstances, only one may in fact be wrong.
