使用代码块

this.searchTerm.asObservable()
        .debounceTime(300)      
        .distinctUntilChanged() 
        .switchMap(term => this.doFind(term))
        .subscribe(data => {
           this.results = data;
           console.log('data', data);
        })
        , error => {
            this.errorMessage = error;
        });

或do运营商

 this.searchTerm.asObservable()
        .debounceTime(300)      
        .distinctUntilChanged() 
        .switchMap(term => this.doFind(term))
        .do(val => condole.log(val))
        .subscribe(data => this.results = data
        , error => {
            this.errorMessage = error;
        });
