So actually this phrase is "kw1 & kw2 kw3"
GA says that "kw1 & kw2" got 300 hits in the last month from Yahoo geolocated to Huntington Beach and Long Beach.
The raw logs show not a single search for "kw1 & kw2 kw3". There are rather three searches for "kw1 & kw2" and one search for "kw1 & kw2 kw3 kw4"
So to answer your question - very inaccurate it would appear. The question is why?
