Steps to reproduce:
* define a searchable custom field boolean
* go to the search page
Example definition:
```
"our.customfield": {
"name": "Supportfall",
"type": "bool",
"search": true
}
```
== What happens ==
At the moment you can only skip the filter, or require a true value:
{F269265}
== What should happen instead ==
Allor to filter by "not true". That is: the elements that does not have that to true.
