Algolia Search API Client for Go

Algolia Search is a hosted full-text, numerical, and faceted search engine capable of delivering realtime results from the first keystroke.

The Algolia Search API Client for Go lets you easily use the Algolia Search REST API from your Go code.

Build Status Supported version

Migration note from v1.x to v2.x

In June 2016, we released the v2 of our Go client. If you were using version 1.x of the client, read the migration guide to version 2.x. Version 1.x are no longer under active development. They are still supported for bug fixes, but will not receive new features.

You can find the full reference on Algolia's website.

Getting Started

Install

Download AlgoliaSearch using

go get github.com/algolia/algoliasearch-client-go/algoliasearch

Quick Start

In 30 seconds, this quick start tutorial will show you how to index and search objects.

Initialize the client

To begin, you will need to initialize the client. In order to do this you will need your Application ID and API Key. You can find both on your Algolia account.

import "github.com/algolia/algoliasearch-client-go/algoliasearch"

client := algoliasearch.NewClient("YourApplicationID", "YourAPIKey")
index := client.InitIndex("your_index_name")

Push data

Without any prior configuration, you can start indexing 500 contacts in the contacts index using the following code:

index := client.InitIndex("contacts")
content, _ := ioutil.ReadFile("contacts.json")

var objects []algoliasearch.Object
if err := json.Unmarshal(content, &objects); err != nil {
  return
}

res, err := index.AddObjects(objects)

Configure

Settings can be customized to fine tune the search behavior. For example, you can add a custom sort by number of followers to further enhance the built-in relevance:

settings := algoliasearch.Map{
  "customRanking": []string{"desc(followers)"},
}

res, err := index.SetSettings(settings)

You can also configure the list of attributes you want to index by order of importance (most important first).

Note: The Algolia engine is designed to suggest results as you type, which means you'll generally search by prefix. In this case, the order of attributes is very important to decide which hit is the best:

settings := algoliasearch.Map{
  "searchableAttributes": []string{
	"firstname",
	"lastname",
	"company",
	"email",
	"city",
	"address",
  },
}

res, err := index.SetSettings(settings)

Search

You can now search for contacts using firstname, lastname, company, etc. (even with typos):

// Search by firstname
res, err := index.Search("jimmie", nil)

// Search by firstname with typo
res, err = index.Search("jimie", nil)

// Search for a company
res, err = index.Search("california paint", nil)

// Search for a firstname & company
res, err = index.Search("jimmie paint", nil)

Search UI

Warning: If you are building a web application, you may be more interested in using one of our frontend search UI libraries

The following example shows how to build a front-end search quickly using InstantSearch.js
