Setup of synonyms and aliases
You can setup synonyms, aliases or alternate names with the web user interface thesaurus manager.
Just add a name or concept with the synonym as an alias or import a thesaurus or ontology with synonyms to the ontologies manager.
After that the module SKOS to Solr adds all alternate SKOS labels or aliases from thesaurus entries as synonym for their prefered labels to the synonym config file for Solr synonym filter.
Please donate so we can integrate (technically existing) features with open data from Wiktionary, so most synonyms and more forms of irregular verbs ("went" is not only "go" with a suffix) will be preconfigured out of the box.
