@netmeg I get different results too. I think that - in addition to this supplementary index (kudos on the -jidjwaos tip by the way, I just tried it and it works very well!), the Google results are also spread out over more than one database.
And it seems like each database isn't fully in sync.
I've got a fairly new site (Google's known about it for 19 days now) and whenever I do a site: search (without the -typo tag), the number of pages returned varies loads.
So yeah, I wouldn't worry about it. Just seems like Google are splitting things up more (perhaps since it's quicker to perform searches; i.e. Google were planning ahead with regards to Google Instant?) and as a result, inconsistent results are more likely.
