Okay, the reason that you're getting one result is that everything that you're doing is intended to operate on only one element. Array.find(), for instance, is basically the JS version of .FirstOrDefault(). Array.indexOf() is a single element as well.

export interface SubCategorySearchResults {
  subCategory: SubCategories;
  foundIn: string;
}
export class SubCategories {
  Id: string;
  Name: string;
  Description: string;
  CreatedBy: string;
  CreatedOn: Date;
  UpdatedOn: Date;
  Selected: boolean;
}

// And produced this JSON
