> FSTLookup currently has a "num" parameter which limits the number of completions from the underlying automaton. But this has severe disadvantages if you need to collect completions that need to fulfill a secondary condition (for example, collect only verbs or terms that contain a certain infix). Then you can't determine the 'num' parameter easily because the number of filtered completions is unknown.
> I also think implementation-wise it's also much nicer to provide a stream that iterates over completions rather than a fixed-size list. This allows for much more elegant code (stream.filter, stream.limit).
> The provided patch adds a single {{Stream<Completion> lookup(key)}} method and modifies the existing lookup methods to use it.
