Subject: Lucene suggester can't suggest similar phrase

Hi,

I am using Lucene 4.10 suggester which I thought can return similar phrase.
But it turned out the different way.

My code is as follow:

public static void main(String[] args) throws IOException {

String path =3D "c:/data/suggest/dic.txt";

Dictionary dic;

dic =3D new FileDictionary(new FileInputStream(path));

InputIterator it =3D dic.getEntryIterator();

Analyzer analyzer =3D ERAnalyzer.getInstance().getAnalyzer();

FuzzySuggester suggester =3D new FuzzySuggester(analyzer);

suggester.build(it);

CharSequence cs =3D "=E9=9B=85=E8=AF=97=E5=85=B0=E9=BB=9B";

List<LookupResult> results =3D suggester.lookup(cs, false, 1);

System.out.println(results.get(0).key);

}

The dictionary contains only one line:

=E9=9B=85=E8=AF=97=E5=85=B0=E9=BB=9B 50

When cs is exactly "=E9=9B=85=E8=AF=97=E5=85=B0=E9=BB=9B", I get the result=
. But when cs is "=E9=9B=85=E6=80=9D=E5=85=B0=E9=BB=9B", which
is only one word different from the target, I get nothing back.

I tried FuzzySuggester as well as AnalyzingSuggester. The result is the
same.

Did I miss something here?

Thanks!
