Michael McCandless commented on LUCENE-3832:
--------------------------------------------

Sorry, what I meant was: we already have (and use, from tests only) this algorithm, in {{lucene/test-framework/src/java/org/apache/lucene/util/automaton/DaciukMihovAutomatonBuilder.java}}.

I agree we should promote it to core: it seems quite useful!

Actually I think there are slight differences vs the attached patch (looks like Robert cutover to CharsRef/BytesRef), so I guess we need to reconcile those... or maybe just move the existing one from test-framework to StringUnionOperations (if there are no *important* differences :) ).

> Brics has my code to build Automaton from a set of sorted strings in one step (Daciuk/Mihov's algorithm again). This should be easily portable to Lucene and is quite useful.
