Yea, I've been trying various searches to get this to work and it still seems... broken.
Merlin Mann talks about using this feature ALL THE TIME on various podcasts and posts, but between Google's searches and the implementation in OF it just doesn't work.
MM gives an example of traveling a lot, utilizing a location-based context example of "steak". There's NO WAY this works as he discusses (finding him a restaurant via the map view that serves steaks) without including places that sell steak knives, a butcher shop, etc. Hell, we can't even get a search for hardware stores to work!
Example Search: Lowe's OR "Home Depot" OR "Ace Hardware" OR hardware -"Restoration Hardware"
Kicks back an Advance Auto Parts store. Then I try to cull the search results down but in the end you end up with something that looks like this:
"home depot" OR "Lowes" OR "Ace Hardware" OR hardware -"Restoration Hardware" -lumber -plumbing -"advance auto parts" -timber -food -computer
And now we're gaming the game and it just doesn't work.
Suggestions? I'd really like to use these for "anywhere contexts" that automagically update via Google searches (new stores, old stores removed, traveling, etc) - but instead it looks like I'm going to just create local-based searches with known address to stores that I frequent (but even then, currently, parent contexts do not share all addresses associated with child contexts!).
