Description

It would be nice to have a Context Aware Suggester (i.e. a suggester that could return suggestions depending on some specified context(s)).

Use-cases:

• location-based suggestions:
  • returns suggestions which 'match' the context of a particular area
    • suggest restaurants names which are in Palo Alto (context -> Palo Alto)
• category-based suggestions:
  • returns suggestions for items that are only in certain categories/genres (contexts)
    • suggest movies that are of the genre sci-fi and adventure (context -> [sci-fi, adventure])
