# Searching and Filtering

Once you have built out your landing page, you will want to give your customers ways to filter by category and to search for a specific type of product. To do this, you will use the same **menu-products-demo** index, but you will also use various attributes to filter or search those products.

## Filtering

In order to filter, you will first need to retrieve a list of categories (or facets) that users may want to filter by. You can do this with the following query.

```javascript
const productsIndex = searchClient.initIndex('menu-products-demo');
productsIndex.search('', { filters: 'store_id:5, facets: ['*'] }).then((results) => { 
  // Your code here 
});
```

An example return would be:

```json
{
  kind: { 
    flower: 106, 
    edible: 67, 
    extract: 28, 
    vape: 22, 
    tincture: 12, 
    topical: 11, 
    'pre-roll': 4 
  },
  activities: { 
    'Ease my mind': 14, 
    'Get relief': 6, 
    'Get some sleep': 4, 
    'Hang with friends': 4, 
    'Get Active': 1, 
    'Stimulate my mind': 1 
  }
}
```

After you have a list of categories, you can filter by category by using one of the facets in a search. For example, to filter by "flower" products for the activity "Ease my mind", you would use the following query:

```javascript
const productsIndex = searchClient.initIndex('menu-products-demo');
productsIndex.search('', { 
  filters: 'store_id:5 AND kind:flower AND activities:"Ease my mind"' 
})
  .then((results) => { 
  // Your code here 
});
```

For more information on composing filters, see the [Algolia docs](https://www.algolia.com/doc/api-reference/api-parameters/filters/).

## Searching

In addition to filtering, you may also want to search. To search, you just include a value for the `search` parameter, which would typically be what the customer enters in the search box. For example:

```javascript
const productsIndex = searchClient.initIndex('menu-products-demo');
productsIndex.search('a', { 
  filters: 'store_id:5 AND kind:flower' 
}).then((results) => { 
  // Search all flower product name/descriptions for 'a' 
});
```
