Is it possible exclude an entry type from result of craft.entries? I would like to fetch all entries apart from those of a specific type: 'chapter'. How do I achieve this with a standard call to 'craft.entries'?

{% set results = craft.entries({
  'search': query,
  'order': 'score'
}) %}
Going through Craft's docs, I found no easy or official way to do this. Fastest possible way, in my opinion:

{# get all section IDs #}
{% set sections = craft.sections.getAllSections() %}

{# get all entry types for sections #}
{% set entryTypes = [] %}
{% for section in sections %}
    {# exclude the entry type you don't want, add the others to 'entryTypes' variable
       you could, of course, replace handle by ID or whatever you like #}
    {% for entryType in section.getEntryTypes() if entryType.handle != 'handleToExclude' %}
        {% set entryTypes = entryTypes | merge([entryType]) %}
    {% endfor %}
{% endfor %}

{% set entries = craft.entries.section('inhoud').type(entryTypes) %}
