A few days ago I posted (removed because off-topic / too specific) that places had gone for some queries on one of my UK sites.
If I typed in London Widgets, previously place names could potentially generate 20 entries. From a few days ago, none are generated.
This was important for my site because there was actual an "thing" called London Widget. What Google was previously doing was providing results for Widgets in London - definitely not the same thing.
