Algolia Search is a hosted 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.
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.
This API client is compatible with Go 1.7 and above.
Download the Go client using:
go get github.com/algolia/algoliasearch-client-go@v2In 30 seconds, this quick start tutorial will show you how to index and search objects.
To start, you need to initialize the client. To do this, you 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", "YourAdminAPIKey")
index := client.InitIndex("your_index_name")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)You can customize settings to fine tune the search behavior. For example, you can add a custom ranking 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: Algolia is designed to suggest results as you type, which means you'll generally search by prefix. In this case, the order of attributes is crucial to decide which hit is the best.
settings := algoliasearch.Map{
"searchableAttributes": []string{
"firstname",
"lastname",
"company",
"email",
"city",
"address",
},
}
res, err := index.SetSettings(settings)You can now search for contacts by firstname, lastname, company, etc. (even with typos):
// Search for a first name
res, err := index.Search("jimmie", nil)
// Search for a first name with typo
res, err = index.Search("jimie", nil)
// Search for a company
res, err = index.Search("california paint", nil)
// Search for a first name and a company
res, err = index.Search("jimmie paint", nil)Warning: If you're building a web application, you may be interested in using one of our front-end search UI libraries.
The following example shows how to quickly build a front-end search using InstantSearch.js
