Did you try 'foo "and"' ?

If you want to do this I think you'd better go with a Keyword index, 
with FieldIndex you shall be able to ask for a range eg (1,4) for 1, 2, 3, 4

You may look at zope/index/field/README.txt or 
zope/index/text/textindex.txt even if its  low-level documentation

Hope it helps,
