Otis Gospodnetic commented on SOLR-81:
--------------------------------------

Adam:

I can merge our patches to produce a unified one.

NOTE:
The SpellCheckerCommitRequestHandler assumes that:
  a) one wants to populate the spellchecker index with data from another Lucene 
index.
  b) the Lucene index to be used for populating is available on the same box 
where the spellchecker service is running.

I think both a) and b) are good - let those who want this functionality have it.
However, some may not be able to live with these assumptions (e.g. one may want 
to have a server dedicated to spellchecker service, and may not want to push 
the source Lucene index to the spellchecker box.)  For those people, the 
approach that includes schema.xml modifications will be required, unless I'm 
missing something.  Am I?

Also, I think this is a mistake:

accuracy = p.getFloat("accuracy", DEFAULT_NUM_SUGGESTIONS);

You probably wanted DEFAULT_ACCURACY there, but that doesn't exist yet, so I'll 
fix that.
