Michael McCandless updated LUCENE-7686:
---------------------------------------
Attachment: LUCENE-7686.patch
Another iteration ... it was trickier than I first realized because I have to
handle the case where another (later) segment has the same suggestion with a
better score, and replace the previous one in the priority queue.
So I broke out the dedup handling to a separate collector,
{{DeduplicatingTopSuggestDocsCollector}}.
And I added a new randomized test case in addition to the dedicated specific
test case.
I think it's ready.

> Some of the other suggesters have this ability, and it's quite simple to add
> it to the NRT suggester as long as the thing we are filtering on is the
> suggest key itself, not e.g. another stored field from the document.
