Would you perhaps be better off creating multiple documents?

Doc 1
ordernumber =3D 1
product =3D apple
quantity=3D100

Doc 2
ordernumber =3D 1
product =3D banana
quantity=3D2000

Doc 3
ordernumber =3D 1
product =3D carrot
quantity=3D35

Then a search could be done 'where order number =3D 1' and you have no worr=
ies about correlated arrays.

Subject: multiple values in a field

Let's say I have three fields in a document: ordernumber, product, quantity=
.

For every ordernumber, I can have several products and corresponding quanti=
ty.

ordernumber =3D 1
product =3D ['apple','banana','carrot']
quantity=3D[100,2000,35]

Would Lucene preserve the order in which values are added to a field within=
 a document?  i.e. apple will be first value, banana will be second and so =
forth?

In my tests, order is preserved and I am able to retrieve values back from =
a document in the same order I added values to it.  But wanted to confirm i=
f this is a guaranteed behavior.

Thx
Chandra
