Angular 2: How to use Observable filter

Question

I have a service that calls the API like this:

return this._http
        .post(appSettings.apiUrl + \'SomeController/SomeAction\', params, {withCredentials:

Here another sample based on @martin's answer:

  public searchMediData(searchtearm: string) : Observable 
  {  

    return this.http
               .get(this.url)
               .map(response => { 
                  let data = response.json();
                  let medidata = data as MediData[];
                  return medidata;
                })
                .concatMap(array => Observable.from(array))
                .filter(medi => {
                        let searchTearmUpperCase = searchtearm.toUpperCase();
                        let mediNameUpperCase = medi.Name.toUpperCase();                       
                        return mediNameUpperCase.includes(searchTearmUpperCase);
                 })
                .toArray();
  }
