Hi Carlos

I am interested in your implementation of FSTLookup where you are using a FST with ByteSequenceOutputs. Would it be possible for you to share your implementation.

Thanks
Sudarshan

> The FST uses a single contiguous byte[] under the hood, which in java is indexed by int so we cannot grow this over Integer.MAX_VALUE.  It also internally encodes references to this array as vInt.
> We could switch this to a paged byte[] and make the far larger.
> But I think this is low priority... I'm not going to work on it any time soon.
