full-text-search

I have a Product table with the fields Id, Title, Description, Keywords (just comma separated list of keywords).

Table is full-text indexed.

When I view one product, I do a query and search the full-text catalog for any related products based on the Keywords field.

select * from Products where Contains(Products.*, @keywordsFromOneProduct)

Works like a charm.

Now I would like to list all products and all their related products in a big list and I want to avoid calling this method for each item.

Any ideas how could I do it? I was thinking about a job that would go through products one by one and build a one-many mapping table (fields ProductId, RelatedProductId), but I wonder is there a better way?
