Here is the the one that uses new token stream api:
public final class CustomFilter extends TokenFilter {
private final TermAttribute termAtt;
public CustomFilter(TokenStream in, FastZemberek zemberek) {
super(in);
termAtt = (TermAttribute) addAttribute(TermAttribute.class);
}
public final boolean incrementToken() throws IOException {
if (input.incrementToken()) {
String term = termAtt.term();
String s = term.replaceAll(":|,|\\(|\\)|“|~|;|&|\\.","");
if (s != null && !s.equals(term))
termAtt.setTermBuffer(s);
return true;
} else {
return false;
}
}
}
