我创建了一个搜索栏，并从mongodb返回结果。我想显示搜索数据的下拉列表，并单击每个下拉列表。

我尝试在结果部分中创建，但没有成功。我还尝试创建一个，并将结果放在该部分中，但它仅显示单词link。

\\ I tried this but it just returned the word r.link:

<ng-template #rt let-r="result" let-t="term">
  <a href='r.link'><ngb-highlight [result]="r.title" [term]="t"></ngb-highlight></a>
</ng-template>

\\ I also tried this but it broke it
<ng-template #rt let-r="result" let-t="term">
  <ngb-highlight [result]="<a href='r.link'>r.title</a>" [term]="t"></ngb-highlight>
</ng-template>

\\ I would like to add a link to this dropdown for each title.
\\ This is my html file

<ng-template #rt let-r="result" let-t="term">
  <ngb-highlight [result]="r.title" [term]="t"></ngb-highlight>
</ng-template>

<div class="row">
    <div class="col-xl-12">
      <div class="row">
        <div class="form-group col-md-12">
          <input id="search" name="search" [ngbTypeahead]="search" type="text" placeholder="Search for solutions..." class="form-control-search-bar form-control-underlined amcs-search" [resultTemplate]="rt" [inputFormatter]="title">
        </div>
      </div>
    </div>
</div>

\\ This is my search.component.ts


search = (text$: Observable<string>) =>
      text$.pipe(
        debounceTime(300),distinctUntilChanged(),tap(() => this.searching = true),switchMap(term =>
          this._service.search(term).pipe(
            tap((searchResults) => { this.searchFailed = false; }),catchError(() => {
              this.searchFailed = true;
              return of([]);
            }))
        ),tap(() => this.searching = false)
      )

      title = (x: {tag: string}) => x.tag;


Any help would be appreciated. Thank you
