You can either search the items in the basket for each item returned by the
search page OR you can turn the search page into a basket page.  The
former approach gets confusing: say they already have 3 of a particular
item in the basket.  Does it show 3?  or if they put in 1 does that mean
they want 1 more or only one.  If they have already got three and
it shows three and they submit that do they get six?  How do you make
that clear?  In the cases where we do that we never add to those items
in the basket, only replace quantities.

Modifying the basket is probably easier, at least where there is 
a limited item count.  Put all the items from your search into the 
basket; use mv_order_item and mv_order_quantity.  Items in the basket
and in search will show twice; you might use perl to remove any items
in the basket from search results.  I don't know how to do that without
perl.
