This implies "we do ignore the terms that are not quoted", which has been a common source of grievance with Google.
Planning your trip ahead, you search for pizza restaurant Chicago. Google ignores 2/3 of your terms and returns local restaurants that serve Vietnamese.
We don't support quoted restriction for local results -- results in a local box -- as the post explains. It also says that's something we're looking at for a further improvement.
What is "a local box"? It sounds like GP was performing a regular web search. Surely you don't mean you ignore quotes just because I put the name of a city as a search term.
No, we don't. Which is why I specifically said local box (it's when we show local results almost always with a map -- the post explains this more). If it's a regular web search, and these are web pages about a local place, quotes work the same as with any web page.
