Quick Start with the API Client

Install

Install the Python client using pip:

pip install --upgrade algoliasearch

Quick Start

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

Initialize the client

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.

from algoliasearch import algoliasearch

client = algoliasearch.Client("YourApplicationID", 'YourAPIKey')
index = client.init_index('your_index_name')

The API key displayed here is your Admin API key. To maintain security, never use your Admin API key on your front end, nor share it with anyone. In your front end, use the search-only API key or any other key that has search-only rights.

Push data

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

index = client.init_index("contacts")
batch = json.load(open('contacts.json'))
index.add_objects(batch)

Configure

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:

1
index.set_settings({"customRanking": ["desc(followers)"]})

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

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.

index.set_settings({"searchableAttributes": ["lastname", "firstname", "company",
                                         "email", "city", "address"]})

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

# Search for a first name
print index.search("jimmie")
# Search for a first name with typo
print index.search("jimie")
# Search for a company
print index.search("california paint")
# Search for a first name and a company
print index.search("jimmie paint")

Search UI

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
