What you CAN do is:
You know, I've done all that before, but it's never worked well for me.
I dread nadining a primitive (rather than "searching" here) because no matter how precisely, how narrowly, I give the term, I've always ended up with a lot of junk as "results," much of which has nothing to do with the primitive. No matter how narrow the phraseage I use.
And there's another issue; try for example, nadining "cali site: democraticunderground," and you'll get damned little
if anything at all on the bitter old Vermontese cali primitive, which is the objective of the search.
At the same time one gets literally
millions of results for "California," a popular topic over there, based upon the "cali."
