如何在Express.js中实现Algolia？

 ```javascript

 index.saveObject({ /* 要添加的记录对象 */ })

     .then(({ objectID }) => {

         console.log('Record added with objectID:', objectID);

     })

     .catch(error => {

         console.error('Error adding record:', error);

     });

 ```

 ```javascript

 index.partialUpdateObject({ /* 要更新的记录对象 */ })

     .then(() => {

         console.log('Record updated');

     })

     .catch(error => {

         console.error('Error updating record:', error);

     });

 ```

 ```javascript

 index.deleteObject('OBJECT_ID')

     .then(() => {

         console.log('Record deleted');

     })

     .catch(error => {

         console.error('Error deleting record:', error);

     });

 ```

 ```javascript

 index.search('SEARCH_QUERY')

     .then(({ hits }) => {

         console.log('Search results:', hits);

     })

     .catch(error => {

         console.error('Error searching records:', error);

     });

 ```

 请将`SEARCH_QUERY`替换为你想要搜索的查询字符串。
