             Summary: Add Context Aware Suggester
                 Key: LUCENE-5350
                 URL: https://issues.apache.org/jira/browse/LUCENE-5350
             Project: Lucene - Core
          Issue Type: New Feature
          Components: core/search
            Reporter: Areek Zillur
             Fix For: 5.0, 4.7


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])
