I hope this helps, I'm not entirely sure what/how you want to search on the all quotes page, but there seems to be enough power with advanced queries to get you there.

I tinkered a bit and seem to have found a way, but not sure how powerful the searching needs to be. The rule is overboard as it is showing some techniques for grabbing the data, transforming it and making a custom view. There are extra fields that aren't used, but might be easier to update the :view to include extra fields as needed.
