Use DiscPlaces for hyper-local search, specifically to search for posts created using disc-app.com.
A key feature of DiscPlaces is search suggestions based on your location, e.g, if you are in a Walmart, and type Wa in the search box, DiscPlaces will suggest Walmart. If you are searching for sugar, type su and it will suggest sugar, if its nearby.
The results are shown as overlays on a map - click on a thumbnail to get an expanded view of the post.
DiscPlaces also autocompletes on place, which makes it easier to focus the map on a place you want to explore.
DiscPlaces has support for indoor maps - you can select a building level, and see posts just for that level.
Try it out on the British Museum!
