             Summary: [suggest] Make Context Query and Field extensible
                 Key: LUCENE-6702
                 URL: https://issues.apache.org/jira/browse/LUCENE-6702
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/other
    Affects Versions: Trunk
            Reporter: Areek Zillur
            Assignee: Areek Zillur
             Fix For: Trunk


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.
