Areek Zillur commented on LUCENE-5350:
--------------------------------------
Thanks for the feedback!
[~mikemccand]: I was wondering the same thing as I was implementing it. By
intuition I think this should be more compact than the N suggester approach but
I think its best to benchmark it against N separate suggesters (will update
with the benchmark results). Also had another idea of implementing this by
'filtering' the suggestions by contexts supplied at query-time rather than
prefixing the context with the analyzed form. I will play around with both and
benchmark it to see whether this would be useful in practice.
[~ppujari]: Can you expand on the deep learning algorithm part?

> 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])
