[jira] [Commented] (LUCENE-6702) [suggest] Make Context Query and
Field extensible
[ https://issues.apache.org/jira/browse/LUCENE-6702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14646701#comment-14646701 ]
Michael McCandless commented on LUCENE-6702:
--------------------------------------------
Thanks [~areek], patch looks good ... can you give some example use cases
to motivate opening things up via subclassing?
I saw some minor things:
bq. +import java.util.*;
Could you fix your IDE to do keep each import separate? Thanks.
I think toString is now not-so-friendly vs before, since we cutover to
IntsRef contexts key? (IntsRef.toString vs CharSequence.toString).

> ContextSuggestField indexes context information along with
> suggestions, which can be used to filter and/or boost suggestions using
> ContextQuery.
> It would be useful to make ContextSuggestField extensible such that subclasses
> can inject context values at index-time, without having to specify the
> contexts in its ctor.
> ContextQuery can be made extensible by allowing sub-classes to override
> how context automaton is created from provided query contexts.
> Currently, ContextQuery uses a context value of "*" to consider all context values,
> It makes sense to have a dedicated {{addAllContexts()}} instead.
