James Dyer updated SOLR-6297:
-----------------------------
Attachment: SOLR-6297.patch
This version of the patch handles combine suggestions also. This requires
shards to send out a list of the original query terms in the shard-to-shard
response. When putting the response back together, query terms are always
included if they were not part of the original query, even if not all shards
returned them in the spellcheck response. This allows "original" terms
invented by WordBreakSolrSpellchecker to be included in the final response to
the client.

>
> When performing a spellcheck request in distributed environment with the
> WordBreakSpellChecker configured, the shard response merging logic can lose
> some suggestions. Basically, the merging logic ensures that all shards marked
> the query as not being correctly spelled, which is good, but also expects all
> shards to return some suggestions, which isn't necessarily the case. So if
> shard 1 returns 10 suggestions but shard 2 returns none, the final result
> will contain no suggestions because the term has suggestions from only 1 of 2
> shards.
> This isn't the case with the DirectSolrSpellChecker which works properly.
