Slightly off-topic, but I thought this would be a good place to ask.
Are there any word embedding tools which take a Lucene/Solr/ES index as input and output a synonyms file which can be used to improve search recall?

They process Lucene index and create embedded representation of it. Then you can search over that representation for "semantic" matches.
Last time I checked it about a year ago the embedded collection of documents was kept in the memory and the search was implemented by a linear scan. So I suspect it can be slow on very large collection of documents.
