org.apache.lucene.sandbox.search.TokenStreamToTermAutomatonQuery

public class TokenStreamToTermAutomatonQuery extends Object
Consumes a TokenStream and creates an `TermAutomatonQuery` where the transition labels are tokens from the `TermToBytesRefAttribute`.

This code is very new and likely has exciting bugs!
