Implement Autocomplete

Autocomplete provides keyword suggestions to assist users in completing their queries, supplemented by a selection of the most relevant products with the ability to see all products on the search results page. The feature also supports category and popular search suggestions. Please contact Nosto Support to have them enabled for your account.

Example Autocomplete

Check out autocomplete's look & feel guidelines.

When integrating Autocomplete you have the option to directly access the API, or you can use our existing Autocomplete JavaScript library that provides most of the required functionality out of the box.

API Requests

Empty query

To retrieve results for an empty query, you must explicitly set emptyQueryMatchesAll: true in your request. By default, emptyQueryMatchesAll is false and the API does not return any results when the query is empty. Setting it to true enables the API to return default suggestions. This behavior applies to all suggestion types — keywords, categories, and popular searches.

For more details please check the Search request schema

Example query for default popular search suggestions

The query below returns the most popular search terms for the specified account.

query {
    search(
        accountId: "YOUR_ACCOUNT_ID"
        query: ""
        popularSearches: {size: 5, emptyQueryMatchesAll: true}
    ) {
        popularSearches {
            hits {
                query
                total
            }
            total
        }
        query
    }
} 

Highlight

API can return highlights indicating which parts of a keyword match the search query. This HTML can be used to render and emphasize the matching sections during display.

Redirects

Redirects are configured in the search dashboard and can be used to forward users to specific pages depending on what they type into the search field. For example, users searching for "shipping" could be directed to https://example.com/shipping.html.

API only returns redirect url, the actual browser redirect must be implemented by the merchant on keyword selection

Analytics

Nosto Analytics

To analyze user behavior you need to implement tracking. This can be achieved in two different ways, depending on the integration environment:

• JavaScript library (recommended - more convenient, but requires a JavaScript environment).

• GraphQL API (works anywhere).

Google Analytics

Each autocomplete product click should be tracked as a search page virtual view to ensure that the Google Analytics search feature displays the correct conversion rate. For example, if you click any product when the typed query is phone it should track a virtual page view with the URL /search?q=phone (adjust the search path and query parameter to match your search page).

Since a product link click would redirect to a new page, to ensure that Google Analytics has time to send the tracking request, it's recommended to save the search query to local storage and track it on page load.
