Michael McCandless commented on LUCENE-5350:
--------------------------------------------

Thanks Areek!

I have a good use case to play with, too: I want to fix 
http://jirasearch.mikemccandless.com suggestions so that if you've drilled-down 
on a particular project, it suggest issues from that project only.

> 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])
