[ic] Creating relationships between Search Results and DB Field

[Matt]

We have created a new column in our products.txt file 
called "application" and we are looking to include it in our search 
results (instead of the Inventory field).

The results.html document has been modified, but the search results 
table requires an IC command like [item-code].  Where do I create the 
relationship so that I can enter [item-app] and have it list the data 
in the application cell for that product?

Thank You.

(If this is documented a link will work fine too)
