Mikhail Khludnev updated LUCENE-6354:
-------------------------------------
Attachment: LUCENE-6354.patch
can we keep {{nextDoc()}} unchanged and keep this predicate in
{{TwoPhase.matches()}} eg.
{code}
public TwoPhaseIterator asTwoPhaseIterator() {
// suppress check on default values
if(minChildren==1 && maxChildren==Integer.MAX_VALUE){
return null;
}else{
return new TwoPhaseIterator() {
@Override
public boolean matches() throws IOException {
return (getChildCount() >= minChildren && getChildCount() <=
maxChildren);
}
@Override
public DocIdSetIterator approximation() {
return BlockJoinScorer.this;
}
};
}
}
{code}
