Showerthought: a librarian in Tulsa taught me the minus sign trick and it blew my mind
I was stuck hunting down a quote from a 1970s city council meeting in Tulsa and Google kept throwing me junk results. The librarian, Dana, told me to type the exact phrase in quotes and then add a minus sign before words I didn't want, like -blog -newsletter. Found the whole transcript in 2 tries after that. Does anyone else have a dumb simple operator like that which they wish they'd learned earlier?
