Hi Andrea, Thanks very much for your helpful link! Is there a way to contact Hoss?
About that link, I have two doubts: -) I'm using Solr (5.4.1) in schemaless mode, and I can't manage the schema.xml in order to customize the SynonymFilterFactory; -) If I copy my thesaurus in the synonyms.txt file, I lose all the hierarchy terms; According to your experience, these two plugins can be helpful for my purpose? http://redlink.co/adding-semantic-search-to-apache-solr/ http://www.opensemanticsearch.org/ Best, Francesco -- View this message in context: http://lucene.472066.n3.nabble.com/solr-hierarchical-search-hyponyms-hypernyms-tp4298385p4298401.html Sent from the Solr - User mailing list archive at Nabble.com.
