In my 3.6 code I was adding numeric field to my index as follows:
public void addNumericField(IndexField field, Integer value) {
addField(field, NumericUtils.intToPrefixCoded(value));
}
but I've chnaged it to (work in progress)
public void addNumericField(IndexField field, Integer value) {
FieldType ft = new FieldType();
ft.setStored(true);
ft.setIndexed(true);
ft.setNumericType(FieldType.NumericType.INT);
doc.add(new IntField(field.getName(), value, ft));
}
whihc seems neater
In 3.6 I also add to override queryparser to make it work for numeric
range searches, do I still have to do this and if so how do I modify it
to work for
IntField.
