So in the end, you found what you needed but had to dig in and get your hands dirty.
I only see positives since you had to work a bit and try some different options, which...expanded your skillset by default.
There are certainly reasons for a mainline, "hook a brutha up," immediate, no thought required search results...whatever they may be.
But...BUT...when you have to apply multiple instances and inductive and deductive logic for deep searches, you actually apply CRITICAL THINKING skills within a Boolean method. You may end up with some useless extraneous information, but more often than not, additive-branching information, that you can explore immediately or in the future--information which you may have never been exposed to.
I call this my ADHD-OCD CrazyCatGuy Method of research! Which, in in turn, make me consider ADD/ADHD and OCD very POWERFUL skills instead of liabilities. I have both at the mega-ultra fucked-up level, and they make me the Research King from....HELLLLLL!
ROCK ON!
