I would like to perform a search inside for a form page and pass along the result that the user selects with the form.

Okay I have three ways of phrasing my question, pick the one that works the best for you:

• I would like to be able to perform a search inside my form.
• I want to have a form page that would allow the user to search (apache solr) for the node they're interested in (in my case a product in Ubercart) then fill out the rest of the form and submit it with the node id.
• To explain my example a little better. I would like create a form that can search my Ubercart product catalog (nodes) and then put in a price quote in for the part(s) that they select.

Where would I start looking if I wanted to implement something like this? Do you know of any modules that I could look at that already implement something like this.
