For the date fields in the graphql schema I see the filter as:  
modificationDate: [StringFilter]  
fibery/modification-date  
But how to exactly filter on data, things like after, between?

Hi, @4erkas

modificationDate is date time. Please use ISO 8601. Find example below

```auto
{
  findFeatures(modificationDate: {
    greater: "2022-06-28T12:05:49.666Z", 
    lessOrEquals: "2022-06-30T12:05:49.666Z"
}) {
    modificationDate
  }
}

```
