--------------------------------------
{code}
+ if (item instanceof char[]) {
+ sb.append((char[]) item);
+ } else {
+ sb.append(item);

{code}
Can we get something else than a char[]? If no I think we should just
forcefully cast?
Otherwise +1.

> A TokenFilter that emits a single token which is a sorted, de-duplicated set
> of the input tokens.
> This approach to normalizing text is used in tools like OpenRefine[1] and
> elsewhere [2] to help in clustering or linking texts.
> The implementation proposed here has a an upper limit on the size of the
> combined token which is output.
