通过阅读 algolia 文档的这一页：

https://www.algolia.com/doc/api-reference/api-methods/search/

.ts 文件

const searchClient = algoliasearch(
      environment.algolia_application_id,
      environment.algolia_search_api_key
    );
    
    export class ProductsComponent implements OnInit {

      hits: any;

      productsConfig = {
          indexName: 'products',
          searchClient
      };

      OnInit(){
           const index = searchClient.initIndex(productsConfig.indexName);

           index.search('query string', {
                    attributesToRetrieve: ['name','firstname', 'lastname'],
                    hitsPerPage: 50,
            }).then(({ hits }) => {
                console.log(hits); // check the console 
                this.hits = hits;
           });
      }
    }

如果您尝试仅通过 Algolia 索引中的属性检索特定记录，则可以使用 filters。例如，假设您要检索 product_id 为“abcdef”的记录，您可以在 ais-configure 组件上设置过滤器，如下所示：

<ais-configure
  [searchParameters]="{ filters: 'product_id:abcdef' }"
></ais-configure>

请注意，您的 product_id 属性必须在 attributesForFaceting for it to be filterable. You can use the filterOnly modifier if you only need to use it as a filter and never as a facet, for better performance. This needs to be done at the index level, either from your indexing code or directly in the Algolia dashboard. You can follow this guide 中设置才能了解如何操作。
