Thanks, I think I understand the general concept more or less, just not 
how to get it working.

I have been looking at 
http://docs.typo3.org/typo3cms/ExtbaseFluidBook/6-Persistence/3-implement-individual-database-queries.html

And to this example: 
http://ameliasdev.wordpress.com/2014/01/29/implementing-a-filter-navigation-in-typo3-extensions-with-extbasefluid/).

It suggests to create a Demand class, but when I run the code I get a db 
error: 'tx_sffilterdb_domain_model_demand' doesn't exist, so there is 
something wrong with my mapping. But I just don't understand what.


class Demand extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {
	
	/**
  	* @var 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\SF\SfFilterdb\Domain\Model\CatSoort>
  	**/
  	protected $catSoort;
	
	/**
	 * Returns the catSoort
	 *
	 * @return 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\SF\SfFilterdb\Domain\Model\CatSoort> 
$catSoort
	 */
	public function getCatSoort() {
		return $this->catSoort;
	}
}

In the main Items controller:
	public function ajaxListAction(\SF\SfFilterdb\Domain\Model\Demand 
$demand = NULL) {
	
	}

What am I doing wrong????
