Subject [jira] [Commented] (SOLR-2848) DirectSolrSpellChecker fails in distributed environment
Date Mon, 24 Oct 2011 14:59:32 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13134123#comment-13134123

Robert Muir commented on SOLR-2848:
-----------------------------------

But SpellCheckComponent.finishStage() needs to be able to get the StringDistance impl that
was used to generate suggestions during the first stage, then re-compute distances using its
getDistance() method.

This is the part i dont understand... we already have the scores in the results, so why recompute?

> While working on SOLR-2585, it was brought to my attention that DirectSolrSpellChecker
has no test coverage involving a distributed environment.  Here I am adding a random element
to DistributedSpellCheckComponentTest to alternate between the "IndexBased" and "Direct" spell
checkers.  Doing so revealed bugs in using DirectSolrSpellChecker in a distributed environment.
 The fixes here roughly mirror those made to the "IndexBased" spell checker with SOLR-2083.
