Hello,
Further investigation shows the following pattern, for both DirectIndex and wordbreak spellchekers.
Assume that in all cases there are spellchecker results when distrib=false
In distributed mode (distrib=true)
case when matches=0
1. group=true, no spellcheck results
2. group=false , there are spellcheck results
case when matches>0
1. group=true, there are spellcheck results
2. group =false, there are spellcheck results
Do these constitute a failing test case?
Thanks.
Alex.

Hello,
I am debugging the SpellCheckComponent#finishStage.
>From the responses I see that not only wordbreak, but also directSpellchecker
does not return some results in distributed mode.
The request handler I was using had
<str name="group">true</str>
So, I desided to turn of grouping and I see spellcheck results in distributed
mode.
curl 'server1:8983/solr/test/testhandler?q=paulusoles&indent=true&rows=10&shards.qt=testhandler'
has no spellchek results
but
curl 'server1:8983/solr/test/testhandler?q=paulusoles&indent=true&rows=10&shards.qt=testhandler
&group=false'
returns results.
So, the conclusion is that grouping causes the distributed spellcheker to fail.
Could please you point me to the class that may be responsible to this issue?
Thanks.
Alex.

> Project: Solr
> Issue Type: Bug
> Components: SolrCloud, spellchecker
> Affects Versions: 4.0-BETA
> Environment: Linux Debian 6 / SolrCloud with 2 shards and 2 replicas.
> Reporter: Christian Johnsson
> Labels: DirectSolrSpellChecker, bug, spellchecker, suggestions
>
> It seems like spellchecker using solr.DirectSolrSpellChecker doesn't work when grouping results.
> /select?q=mispeled
> Gives me correct spellingsuggestions
> but..
> /select?q=mispeled&group=true&group.main=true&group.field=title
> don't give any suggestions.
> It worked in 3.5 with indexbased spellchecker.
> It seems like if i mispell something that returns 0 results i dont get any suggestions. If i misspell something that genereate a result i get suggestions on it.
> It should come up with proper suggestions even if there are no results to be displayed (But there is things that should be suggested).
> Long story short. Same functionality as in 3.5 :-)
