Good day!

where filter:
public Filter(boolean usefilter, Integer Topprice, Integer Lowprice, SortingPrinciple SortingPrincipl, String Name, Set Idtags){
this.usefilter= usefilter;
this.topprice=topprice;
this.sortingprinciple=SortingPrinciple;

}
public enum SortingPrinciple {
popularity,
price,

Answer 1

The mere presence of a method does not give you the right to call it through GraphQL queries. What and how can be requested - the scheme answers. Actually, you can see the diagram on the screenshots. filter is a named object. In requests, parameters are passed in the following form:

query {
  someQuery(
    argName: argValue,
    ...
  ){
     ....fields
  }
}

Cannot be called as a function like filter(...args)
In your case like this:

query {
  advertisementsByFiltersearch(
    filter: {
      name: "Name"
      usefilter: true
      lowerprice: 300
    }
  ){
     ....fields
  }
}
