Thanks for the answer James. My fault not specifying the Solr version, we are working with solr 4.5.
Anyway, thank you very much for pointing the change to DirectSolrSpellChecker. I hadn't even realized that change, and I think I wasn't using it, as the line "<str name="classname">solr.DirectSolrSpellChecker</str>" was missing in my configuration. Once I changed it, I think everything is working fine even after server restart. Thanks again James, you've saved me from some serious headache ;) 2014-02-05 Dyer, James <james.d...@ingramcontent.com>: > Alejandro, > > Assuming you're using Solr 3.x, under: > > <searchComponent name="spellcheck" class="solr.SpellCheckComponent"> > <lst name="spellchecker"> > ... > </lst> > </searchComponent> > > ...you can add: > > <str name="spellcheckIndexDir">./spellchecker</str> > > ...then the spell check index will be created on-disk and not in memory. > > But in Solr 4.0, the default spellcheck implementation changed to > org.apache.solr.spelling.DirectSolrSpellChecker, which does not create a > separate index for for spellchecking, "build" does nothing, and you need > not worry at all about these things.
