James, Thanks for clearly stating this , I was not able to find this documented anywhere, yes I am using it with another spell checker (Direct) with the collation on. I will try the maxChangtes and let you know.
On a side note , whenever I change the spellchecker parameter , I need to rebuild the index and delete the solr data directory before that as my Tomcat instance would not even start, can you let me know why ? Thanks.
