"Product Search" capability in "Sample Application"

Question

i have just started reviewing the HTML DB product and its rad capabilities.
the "Customer Search" capability is were my interest lies at this time and i am really confused...
as to how it works and how i could go into the "Sample Application" and modify it for a similar...
"Product Search" capability.
can you provide any assistance to me on this matter ?
i had thought that it could be in the user guide somewhere...
but i am only up to page 75 or so and getting impatient/excited.
Thanks in advance.

Note: raj gave me the following info:
hey robert--
if you look at the definition for the two pages you've asked about, 1 and 400, you'll see that page 1 just branches to page 400 after the user submits the page. while the page is being submitted, though, page 1 sets the value of G_CUSTOMER_NAME to whatever was entered for P1_SEARCH. the query region on page 400 simply includes that G_CUSTOMER_NAME predicated in its where clause. there's a simpler but similar example of this in our how-to docs...

...specifically at...
http://www.oracle.com/technology/products/database/htmldb/howtos/dynamic_report.html
...and, you can even simplify that example a little more by using sql instead of a pl/sql function returning that sql. so the sql version could look like...
select p.category,
p.product_name,
i.quantity,
i.unit_price
from demo_product_info p,
demo_order_items i
where p.product_id = i.product_id
and p.category = :p600_show or :p600_show = 'ALL'
...hope this helps,
raj
