Using the JavaScript Library

For client-side/frontend integrations, Nosto's JavaScript library can be used to simplify the integration. It provides a programming interface to access the Search & Categories API.

For the most basic search the fields parameter should be provided to specify what product/keyword fields should be returned. Both products and keywords can be used separately and together, depending on the use case. For all parameters, see the reference.

nostojs(api => {
    api.search({
        query: 'my search',
        products: { fields: ["name"] },
        keywords: { fields: ["keyword"] }
    }).then(response => {
        console.log(response);
    });
});

The api.search function also accepts the following options:​

OptionDefaultDescription

redirect

false

Automatically redirect if search returns a redirect

track

null

Track search query by provided type

The function automatically loads session parameters required for personalization & segments in the background.

In order to request custom fields, add the entries "customFields.key" and "customFields.value" to the requested product fields. This changes the example above like this

// ...
        products: { fields: ["name", "customFields.key", "customFields.value"] },
// ...

Search page

For a search page in most cases the facets parameter should be provided.

Also redirect & track should be enabled to automatically track searches to Nosto analytics & redirect if API returns a redirect request.

nostojs(api => {
    api.search({
        query: 'my search',
        products: {
            facets: ['*'],
            fields: ['name'],
            size: 10
        }
    }, {
        redirect: true,
        track: 'serp'
    }).then(response => {
        console.log(response);
    });
});

Autocomplete

track should be enabled to automatically track searches to Nosto analytics.

nostojs(api => {
    api.search({
        query: 'my search',
        products: {
            fields: ['name'],
            size: 10
        },
        keywords: {
            fields: ['keyword'],
            size: 5
        }
    }, {
        track: 'autocomplete'
    }).then(response => {
        console.log(response);
    });
});

Statistics for autocomplete are being gathered, but they are not currently visible in the Analytics Dashboard.

Category page

For category pages in most cases the facets parameter should be provided. And either categoryId or categoryPath should be also provided.

Furthermore redirect & track should be enabled to automatically track searches to Nosto analytics & redirect if API returns a redirect request.

nostojs(api => {
    api.search({
        products: {
            categoryId: '12345',
            fields: ['name'],
            size: 10
        }
    }, {
        track: 'category',
        redirect: true
    }).then(response => {
        console.log(response);
    });
});

Session parameters

For some of the search features to work properly, such as personalised results and segments, the search function needs to be able to access information about the user's session from the front-end.

The search function of the JS API already includes session state automatically.

To get all session data the following snippet can be used:

nostojs(api => {
    api.getSearchSessionParams(options).then(response => {
        console.log(response);
    });
});

The results of this function should be passed to search query sessionParams parameter. In case search is called from backend, it should pass this data to backend (e.g. using form data).

The function accepts the following options:

OptionDefaultDescription

maxWait

2000

Maximum execution time in MS

cacheRefreshInterval

60000

Maximum cache time

Analytics

Tracking search events to analytics can be divided into three parts: search, search submit, search product/keyword click. These are user behaviours that should be tracked:

  • search submit (type = serp)

  • faceting, paginating, sorting (type = serp) or (type = category)

  • autocomplete input (type = autocomplete)

  • search results product click (type = serp), (type = autocomplete) or (type = category)

  • autocomplete keyword click (type = autocomplete)

  • category merchandising results (type = category)

JS API library provides tracking helpers for all of these cases.

Search

User actions that lead to search results should be tracked with api.recordSearch() after search request is done:

  • search submit (type = serp) - user submits search query in autocomplete component and is landed to SERP

  • faceting, paginating, sorting (type = serp) or (type = category) - user adjusts current search results by filtering (e.g. brand), selecting search page, sorting results

  • autocomplete input (type = autocomplete) - user sees partial results while typing in search input

  • category merchandising results (type = category) - user sees specific category results when category is selected (category merchandising must be implemented)

You don't need to execute api.recordSearch()if you call api.search(query, { track: 'serp'|'autocomplete'|'category'}) function from JS API, becauseapi.search()already calls api.recordSearch() when track option is provided.

nostojs(api => {
    const searchResult = response.data.search

    api.recordSearch(
        type,
        query,
        searchResult
      )
})
ParameterDescription

type

Search type: serp, autocomplete, category

query

Partial search API query containing: query, products.sort, products.filter

searchResult

Partial search API results containing: products.hits.productId[], products.fuzzy, products.total, products.size, products.from

Example:

api.recordSearch(
    "serp",
    {
        query: "shoes",
        products: {
            sort: [{ field: "price", order: "asc" }],
            filter: [{ "field": "brand", "value": "Nike" }]
        }
    },
    {
        products: {
            hits: [{ productId: "123" }, { productId: "124" }],
            fuzzy: true,
            total: 2,
            size: 2,
            from: 0
        }
    }
)

Search form submit

Search queries are categorised into two groups: organic and non-organic searches. In order to mark a search query as an organic search you need to call api.recordSearchSubmit(). You should call it on search input submit only, before search request is sent.

nostojs(api => {
    api.recordSearchSubmit(query)
})

Organic search - is a search query submitted through search input and which lead to SERP (search engine results page). Following faceting, paginating, sorting queries on organic query is also counted as organic.

Search product/keyword click

Product clicks should be tracked in autocomplete component, SERP, category page with api.recordSearchClick() by providing component (type), where click occurred, and clicked product data:

nostojs(api => {
    api.recordSearchClick(type, hit)
})
Parameter

type

Search type: serp, autocomplete, category

hit

Object containing productId and url, collected from clicked product

Example:

api.recordSearchClick(
    "autocomplete", 
    { productId: "123", url: "https://myshop.com/product123" }
)

Product and keyword clicks must be tracked separately by binding to two separate click events.

Keyword clicks should be tracked in autocomplete component with api.recordSearchClick() by providing type = autocomplete and keyword hit object:

nostojs(api => {
    api.recordSearchClick(
        'autocomplete',
        { keyword: 'green' }
    )
})

⚠️ Event Tracking Requirements ⚠️

When tracking events, adherence to the following criteria is essential for capturing detailed and valid data:

  • query parameter:

    • The query string is an essential component for event tracking.

    • If present, include products.sort to track sorting behavior.

    • If applicable, incorporate products.filter.

  • searchResults parameter:

    • products.hits array containing objects with a productId is mandatory.

    • products.total number to identify if the search has results.

    • For accurate pagination tracking, products.from and product.size must be included.

    • For identifying if the request was autocorrected include products.fuzzy.

    • For category requests include either products.categoryId or products.categoryPath.

💡 Tip: In case of API integration, use this example GraphQL partial query to integrate with the API and retrieve the necessary response data for precise event tracking.

query {
  search(
    accountId: "YOUR_ACCOUNT_ID"
    query: "green"
    products: { size: 10, from: 10 }
  ) {
    products {
      hits {
        productId
      }
      total
      size
      from
      fuzzy
      categoryId
      categoryPath
    }
  }
}

🚩 Search Form Submit

Bear in mind that search queries are split between organic and non-organic searches. To classify a search as organic, it is crucial to invoke api.recordSearchSubmit() upon the search input submission, before the actual search request is dispatched. This step is pivotal in ensuring the seamless tracking of organic searches through to the SERP.

🔍 Accurate Click Tracking

Tracking product and keyword clicks is fundamental for understanding user interaction. Use api.recordSearchClick() to monitor these actions correctly, specifying the type and relevant hit data. Remember, product and keyword clicks should be monitored distinctly—never combine the two!
