This happened to me a few years back. I did a Swagbucks search for a local chicken place and received 99 SB! Anyone else ever topped that? Otherwise, for the most part when I get credit for a search it's usually between 5-15 SB points.
I know I have gotten a large number of SB for a search before, but I can't remember how much it was. I want to say it was close to 90 though. I don't do the search through Swagbucks often if at all. I do Microsoft Rewards so I do all my searches through Bing. I get more out of it versus Swagbucks.
The most I have gotten at once is 50 SB and it was for a search about Elvis. I was tickled pink when I got the notice. It is very hard to earn search SB's these days. I try daily. I am never quite able to get all of the collector's bills when they have a contest though.
