Hi everyone,

Probably a quick answer here, but for all of you FTS experts:

Most FTS products do not contain a default synonym dictionary, correct?  
It's up to each installation to derive it's own custom file as it is with  
ES, right? Some commercial search solutions that included a supposedly  
"robust" thesaurus. I guess that is part of the price/package.

Thanks!

You can use the default Wordnet dictionary. Lucene, and therefore  
Elasticsearch, supports the Wordnet file format.

Synonyms are very context specific. What might work for e-commerce might  
not work for a social network.
