# Store Search API Route

In this guide, you'll learn how to expose your search indexes to a storefront through the [Store Search API route](https://docs.medusajs.com/api/store/search/search-indexes), and how to control what a storefront can find in them.

### Prerequisites

- [Medusa v2.21.1+](https://github.com/medusajs/medusa/releases/tag/v2.21.1)

## What is the Store Search API Route?

Medusa exposes a single `POST /store/search` route that searches any index of your application, so you don't create an API route per index. It answers with the search engine's own results, which is the contract the [InstantSearch adapter](https://docs.medusajs.com/resources/instantsearch) is built on.

The route exposes nothing by default. An index is only searchable through it once the `configureStoreSearch` middleware allows it, and a request for any other index is answered as if the index didn't exist. That way, the route never tells a storefront what your application holds.

***

## Allow Indexes on the Route

To allow an index to be searched through the route, apply the `configureStoreSearch` middleware to `/store/search` in `src/api/middlewares.ts`:

```ts title="src/api/middlewares.ts"
import {
  configureStoreSearch,
  defineMiddlewares,
} from "@medusajs/framework/http"

export default defineMiddlewares({
  routes: [
    {
      matcher: "/store/search",
      middlewares: [
        configureStoreSearch({
          allowed_indexes: {
            product: true,
            product_category: true,
          },
        }),
      ],
    },
  ],
})
```

A storefront can now post a query with `"entity": "product"` or `"entity": "product_category"`. Every other index still answers with a `404` error, and Medusa logs why for whoever configured the route.

You can apply the middleware more than once. Each one merges its `allowed_indexes` into the ones before it, so a plugin exposes its own index without discarding what your application allowed.

Only allow indexes whose documents are public. An index holding internal data, such as one you built for [Medusa Admin's search](https://docs.medusajs.com/resources/infrastructure-modules/search/admin-search), stays unreachable from a storefront as long as you don't allow it.

***

## How Medusa Narrows a Product Index

A storefront must never find a draft product, or a product that isn't in the request's sales channel. So, for an index whose `entity` is `product`, Medusa adds the following filters to every query:

|Filter|Applied when|
|---|---|
|\`status\`|The index declares a |
|\`sales\_channel\_ids\`|The index declares a |

So, to have Medusa scope your product index for you, declare both fields in the index definition. `sales_channel_ids` isn't a field of the product itself, so select the product's `sales_channels.id` and flatten them onto the document with a [`transform`](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions#index-part-of-an-entity):

```ts title="src/search/product.ts"
const productFields = search.define({
  id: search.keyword().filterable().retrievable(),
  title: search
    .text()
    .searchable({ weight: 3 })
    .retrievable(),
  // Read by `/store/search` to scope the index.
  status: search.keyword().filterable().retrievable(false),
  sales_channel_ids: search
    .keyword()
    .array()
    .filterable()
    .retrievable(false),
  // ...
})

const source = {
  fields: ["id", "title", "status", "sales_channels.id"],
  transform: (products) => {
    return products
      .filter((p) => p.status === "published")
      .map((product) => ({
        id: product.id,
        title: product.title,
        status: product.status,
        sales_channel_ids: product.sales_channels.map(
          (salesChannel) => salesChannel.id
        ),
      }))
  },
}

export default defineSearchIndex({
  name: "product",
  entity: "product",
  fields: productFields,
  consume: graphConsume(source),
  seed: graphSeed(source),
  // ...
})
```

The `status` and `sales_channel_ids` fields use [`retrievable(false)`](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions/modifiers#retrievable), so the route can filter on them without ever returning them in a hit.

The index in this snippet is simplified to show one feature at a time. For examples of indexing prices in multiple currencies, option values, categories, and other product data, refer to the [Product Index Examples guide](https://docs.medusajs.com/resources/infrastructure-modules/search/product-index-examples).

If the index is missing either field, Medusa logs a warning once for that index and skips that filter. Then, either add the missing field to the definition, or scope the index yourself as explained in the next section.

***

## Filter an Index for Your Storefront

To constrain an index beyond what Medusa applies, pass a `filters` function for it instead of `true`. The function receives the request, so a constraint can depend on who is asking, and it can be asynchronous.

For example, to only find active product categories:

```ts title="src/api/middlewares.ts"
import {
  configureStoreSearch,
  defineMiddlewares,
} from "@medusajs/framework/http"

export default defineMiddlewares({
  routes: [
    {
      matcher: "/store/search",
      middlewares: [
        configureStoreSearch({
          allowed_indexes: {
            product: true,
            product_category: {
              filters: (req) => ({ is_active: true }),
            },
          },
        }),
      ],
    },
    // ...
  ],
})
```

Medusa combines your filters with the ones it applies itself and the ones the storefront posts using an `$and` operator. So, a storefront can narrow its own results but never widen them past what you allowed.

***

## Search Documents in the Storefront

Once an index is allowed, send a `POST` request to `/store/search` with the index's name in `entity`:

```bash
curl -X POST "http://localhost:9000/store/search" \
  -H "x-publishable-api-key: pk_123" \
  -H "Content-Type: application/json" \
  --data '{
    "entity": "product",
    "filters": { "q": "shirt" }
  }'
```

Learn more about the accepted request body and the response in the [Store Search API reference](https://docs.medusajs.com/api/store/search/search-indexes).

To build a full search experience with facets, pagination, and sorting in your storefront, use the [InstantSearch adapter](https://docs.medusajs.com/resources/instantsearch), which posts to this route for you.
