Is it possible to exclude multiple sections from an entry search query? I'm trying to build a search function that excludes results from certain sections all together. This is the code I was trying to use.

{% set entries = craft.entries.search(query).section('not testimonials, not authors').id('not 2').order('score') %}


When I use just one section, it works fine:

{% set entries = craft.entries.search(query).section('not authors').id('not 2').order('score') %}


Any thoughts on how I could construct this query?
The trick is to add and once before the first not

{% set entries = craft.entries.search(query).section('and, not this, not that') %}
