Custom search results I am using drupal 7 built in search  module. In my custom content type, I have multiple products for Industrial,mechanics and sports categories. I need to apply search restriction on some products for my mechanics category. Means If mechanics_product1, mechanics_product2 and mechanics_product3 are mechanics products then I need to apply search restriction on all products for only mechanics_product2. Only authorize user will be only able to search this particular product.
