What comes to mind is 

To search for multiple possible words in the same field, simply add them all in the matching clause.

//search document with storm or lightning in their history
Query luceneQuery =
mythQB.keyword().onField("history").matching("storm lightning").createQuery();
The More Like This implementation also applies Analyzers to create the right corpus. And the algorithm is specific to Hibernate Search and field centric rather that Lucene document centric implementation. Maybe Elasticsearch follows our approach too.
