Update: The search does not work under certain (most) circumstances. On our home page, we display a selection of featured products according to the settings here: /admin/categories.php#featured (Admin -> Catalog -> Categories -> Featured Products). If I click on the home page, then one of the Search by Price links as shown in the code above, then only the featured products within that search's price range are displayed. However, if I run a search using /search.php, then later click on one of the price search links in the code above, then the search displays all products properly. So, I am still without a working Search by Price solution.
