Probably this is trivial question.
How can you enforce the order of the fields when you index them ?
By the order in which you add them to a document.
So when you do the following:
doc.add(Field.Keyword("id", keywords[i]));
doc.add(Field.UnIndexed("country", unindexed[i]));
doc.add(Field.UnStored("contents", unstored[i]));
doc.add(Field.Text("city", text[i]));
The first stored will be id, the second country and so on.
Is that correct ?

No, not if your fields are positioned in the right
order. It stops reading fields after it has got what
is needed.
If your doc has fields in the order:
smallFrequentlyReadField, largeRarelyReadField
then the patch will not read "largeRarelyReadField"
off the disk when you ask for
"smallFrequentlyReadField".
If the fields are ordered the other way around then
there is (currently) no way of knowing the offset of
the smallFrequentlyReadField so all fields would have
to be read.
Hope this helps.
