Title: Advanced search entries relatedTo category and unrelated to any category
ThreadText: # Advanced search entries relatedTo category and unrelated to any category
  
  (Asked by: username_0 on 2017-08-17)
  
  I know the long-form method for achieving my goal, but I'm hitting a wall in trying to keep the conditionals down.
  
  Is it possible to search for entries related to a specific category field **AND** search for entries with no category selection for that same field?
  
  Right now, I can only do the first part. Here's a snippet of a much larger query.
  
  ```
  {# get all categories within specific category groups #}
  {% set skillsOptions = craft.categories.group('skillsCategories') %}
  {% set durationOptions = craft.categories.group('durationCategories') %}
  
  {# working: find all entries with any category selected #}
  {# not working: also find all entries with no category selected #}
  {% set opportunities = craft.entries.section('opportunities').relatedTo('and',
      {
          targetElement: ['or', skillsOptions],
          field: 'skills'
      },
      {
          targetElement: ['or', durationOptions],
          field: 'duration'
      }
  %}
  
  ```
