AddSearch Search API Client for JavaScript

AddSearch is a hosted search platform for all your web content. This API Client lets you easily use the AddSearch Search API from your JavaScript code on web browsers or with Node.js.

Quick Start

The library is available on the global CDN jsDelivr:

<script src="https://cdn.jsdelivr.net/npm/addsearch-js-client@0.1/dist/addsearch-js-client.min.js"></script>

To install the library locally or to use it with Node.js:

npm install addsearch-js-client --save

After installation, add the library to your JS code

var AddSearchClient = require('addsearch-js-client');

Or use import in ES6

import AddSearchClient from 'addsearch-js-client';

Execute the first search query

// Create client with your 32-character SITEKEY
var client = new AddSearchClient('YOUR PUBLIC SITEKEY');

// Callback function
var cb = function(res) {
  // Print results to console
  console.log(res);
}

// Execute search. Callback function will be called with search results
client.search('keyword', cb);

Publicly accessible functions

The client provides the following functions.

Fetch search results

// Search with a specific keyword
client.search('keyword', callback);

// Search with the previously used keyword or execute a "match all" query
client.search(callback);

// Search with the previously used keyword and callback (e.g. after modifying filters)
client.search();

Fetch search suggestions

// Configure Search suggestions on AddSearch Dashboard first
// Get suggestions starting with a specific prefix
client.suggestions('a', callback);

Number of search suggestions

// Number of search suggestions to fetch (default 10)
client.setSuggestionsSize(20);

Search with fuzzy matching

// Enable/disable fuzzy matching. Possible values true/false/"auto" (default: "auto")
client.setFuzzyMatch(false);

Set JSON Web Token (for authentication)

// Add JWT to the search request (if protected search index)
client.setJWT(token);

Set user token (for personalized search results)

// Add a user token to the search request (if personalization in use)
client.setUserToken('uuid');

Send personalization events with search query

In personalized search, user events are typically sent to AddSearch via API and a user token is passed with the search query (see setUserToken function). An alternative way is to send user events needed for personalization with the search query.

// Events depend on the personalization strategy
// Contact AddSearch for more information
var events = [
  {favorite_genre: 'rock'},
  {favorite_band: 'Red Hot Chili Peppers'},
  {least_favorite_genre: 'country'}
];

client.setPersonalizationEvents(events);

Define language filter

// Documents in specific language (e.g. "en" or "de")
client.setLanguage('en');

Define publishing date filter

// Documents published between specific date range
client.setDateFilter('2019-01-01', '2019-01-31');

Define price range filter

// Products in specific price range (in cents. e.g. 100,00 - 200,00)
client.setPriceRangeFilter('10000', '20000');

Define category filters

Filter by URL patterns, document types or addsearch-category meta tag values. See the full documentation.

// Only PDF files or products
client.setCategoryFilters('doctype_pdf,products');

Custom field filters

Filter by custom fields. Custon fields can be defined in meta tags or AddSearch crawler can pick them up from your HTML or JSON data. See the full documentation.

// Search by specific city (Berlin, Paris or Boston)
client.addCustomFieldFilter('city','berlin');
client.addCustomFieldFilter('city','paris');
client.addCustomFieldFilter('city','boston');

// Remove Paris (Berlin and Boston remaining)
client.removeCustomFieldFilter('city','paris');

// Remove all cities
client.removeCustomFieldFilter('city');

Manage paging

Set page number, page size and sorting parameters. It's possible to order results by:

• relevance (descending)
• date (ascending or descending)
• custom field value (ascending or descending. E.g. custom_fields.price)

// Defaults: page "1", pageSize "10", sortBy "relevance", sortOrder "desc"
client.setPaging(page, pageSize, sortBy, sortOrder);

Other functions.

// Next page (call search function to fetch results)
client.nextPage();

// Previous page
client.previousPage();

Set result type

// By default, fetch all search results
// If "organic", Pinned results and Promotions are left out
client.setResultType('organic');

Facets

// Declare fields for faceting. Number of hits found from
// these fields will be returned
client.addFacetField('category');
client.addFacetField('custom_fields.genre');

By default, 10 facets with most hits are returned per field. Use the following function to get more or less facets.

client.setNumberOfFacets(20);
