joins with text search

hi-

supposing i have the following table structure:

vendors
- id int
- name varchar

products
- product_list_id int
- vendor_id int references vendors
- part_number varchar
- description varchar
- price
- textsearch

how can i execute some type of join and get the name of the vendor to be
included in the textsearch column of the products table?

i am currently populating the textsearch column with the following
command:

UPDATE
products
SET
textsearch=setweight(to_tsvector('english', description), 'A') ||
setweight(to_tsvector('english', part_number, 'B')
WHERE
product_list_id=3

Is there a way I can join products.vendor_id with vendors.id and get the
vendor.name in the textsearch column as well?

Thanks,
Clark
