Can you direct me to the API how to access these cached values? I'd like to have a function like: "List all unique values of the categories (A, B, C...) for documents that match this query". i.e. for a query "text:john" show up categories=(A,B) Doc 1: category=A text=john Doc 2: category=B text=mary Doc 3: category=B text=john Doc 4: category=C text=mary This is intended for search refinement (I use about 200 categories). Sorry for hijacking this thread.
