Display non search results in Drupal 7 I've been looking for a way to show all taxonomy terms that are not searched for in a view.

What I mean is: I want a search to sort out safe food for customers that are allergic to some food. If a customer is allergic to nuts the customer type nuts in the form and the customer gets a list of all dishes that DON'T contain nuts. Anyone know a module that will help me do this?
Sure, you can do this with Views.


Build a view that displays your dishes.
Set a FILTER for 'Has taxonomy term', expose it, and use the 'is none of' operator




I made that example using the 'dropdown' option, you may find the 'autocomplete' option more suitable to your needs.  I recommend trying both to see which fits best and allowing multiple values so that people who are allergic to nuts AND gluten can still use it.
