Do you know if I can get synonyms.txt files for all languages supported by SOLR ? Thanks for your help. Before we were using Verity that provide a dictionary of synonyms for each language supported but we want maybe to move to Solr/Lucene. I know that we can provide a custom synonym list that is no what I want. I am looking for a way to have a default dictionary of synonyms for each language supported by Lucene.
There is no 'out of the box' synonym resource provided for all the languages. At least for some, you have wordnet (which is free) - see the solr wiki for wordnet usage.
