Areek Zillur updated LUCENE-5350:
---------------------------------
Attachment: LUCENE-5350.patch
Initial (rough) Patch:
- Add contexts and hasContexts to InputIterator
- Add support to Analyzing suggester to handle contexts
- Add new ContextAwareSuggester (proxies Analyzing Suggester)
- Add tests for ContextAwareSuggester
TODO:
- The patch "breaks" the Lookup API (I think its better to have LookupOptions
that encapsulates the query-time input to suggesters)
- Add context and hasContexts support to all impl of InputIterator
- General refactoring
- Add FuzzySuggester support
- Add docs
This patch demonstrates the idea; If the approach makes sense, the appropriate
changes to the API will be the next task. Feedback, thoughts welcome! It would
also be nice to figure out a way so that we dont have to subclass
AnalyzingSuggester to 'use' it.

> 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])
