An Example Concept Expression that Affinder helps developers construct
Desired Concept to Express: "Open space for play", maybe such as place to toss a frisbee. Available Context Features? Place/Categories/Reviews, Weather, Time
(Asking Convo Assistants for "Whats a nice open space for play when I visit Evanston IL", why do we need this representation for retrieval, rather than what current search engines tell us?)
Obstacle - Top Down: No available context features that detect "open space"
Intermed. Concept: Start with parks (open grassy fields)
Running
Affinder depends on affinder-search to be running. Make sure updateYelpCategories is pointing to a running instance of affinder-search's search_yelp_categories_server.py
The URL of the Affinder-Search server can be set with the environment variable AFFINDER_SEARCH_URL
To connect to ce-platform, we run affinder by connecting to the ce-platform database, i.e.
MONGO_URL=mongodb://user:password@localhost:27017/meteor meteor
Backing up database

Folder Organization
client/template/workspace.html: This is the overall view, which links out to other client html/js templates (feature discovery, blockly workspace, simulating yelp business instances)
server/methods.js has some helpful Meteor methods (think of them sorta of like API routes) that get access to database level information through internal HTTP requests. Used for the unlimited vocabulary search.
