I fixed this problem by writing an external Java class and changing completly
to Lucene-2.4.0.
The SpellChecker now returns results but it is very slow.
My index contains about 20000 words, I don't think this is too much.
How can I speed it up?
My temporary method:
public static Vector suggest(String query, String indexName, String field,
float accuracy) {
Vector v = new Vector();
String[] suggestions = null;
try {
SpellChecker spellchecker = new SpellChecker(new
RAMDirectory()/*, new
JaroWinklerDistance()*/);
spellchecker.indexDictionary(new
LuceneDictionary(IndexReader.open(indexName), field));
spellchecker.setAccuracy(accuracy);
suggestions = spellchecker.suggestSimilar(query, 5);
} catch (Exception e) {}
for(int i = 0; i < suggestions.length; i++) {
v.add(suggestions[i]);
}
return v;
}
