Not documented: how to get fulltext indexing not to drop hyphens

Full text indexing (Indexes for full-text search - Neo4j Cypher Manual ) works well for me except the default analyzer strips hyphens from indexing.

Consider that the search for "Emergency" should not return "Non-Emergency". Product codes often have dashes in them too.

This is actually a lucene question/issue. I did find this:

So this works:

CALL db.index.fulltext.createNodeIndex("IndexName",["Label"],["property"], 
{ analyzer: "classic"}) // does not throw out hyphens, e.g. Non-Emergency is one word

This doesn't seem to be documented in the Neo4J documentation.
