# Get trending items

> Retrieve global trending items.

export const Legacy = ({title, href}) => {
  return <Note>

    This page documents an earlier version of the API client.
    For the latest version, see <a href={href}>{title}</a>.

    </Note>;
};

<Legacy title="Retrieve recommendations" href="/doc/libraries/sdk/methods/recommend/get-recommendations" />

**Required ACL:** `search`

<Note>
  This method is only available in the JavaScript API client.
</Note>

Retrieve trending items for a specific facet when you pass `facetName` and `facetValue`.

## Examples

```js JavaScript icon=code theme={"system"}
recommendClient
  .getTrendingItems([
    {
      indexName: "INDEX_NAME",
      threshold: 80,
      facetName: "category",
      facetValue: "sweaters",
    },
  ])
  .then(({ results }) => {
    console.log(results);
  })
  .catch((err) => {
    console.log(err);
  });
```

### Response as JSON

This section shows the JSON response returned by the API.
Each API client wraps this response in language-specific objects, so the structure may vary.
To view the response, use the `getLogs` method.
Don't rely on the order of properties—JSON objects don't preserve key order.

```jsonc JSON icon=braces theme={"system"}
{
  "results": [
    {
      "hits": [
        {
          "_highlightResult": {
            "category": {
              "matchLevel": "none",
              "matchedWords": [],
              "value": "Men - T-Shirts"
            },
