Antonio Bruno commented on LUCENE-749:
--------------------------------------
It would have in this way to be:
...
- if (logic == AND)
+ if (logic == AND || logic == ANDNOT)
{
result = (BitSet) chain[i].bits(reader).clone();
++i;
}
else
{
result = new BitSet(reader.maxDoc());
}
for (; i < chain.length; i++)
{
doChain(result, reader, logic, chain[i]);
}
return result;
...
> ChainedFilter does not work well in the event of filters in ANDNOT
