Algolia Basics
Introduction
Algolia is a powerful hosted search engine that provides fast and relevant search experiences for users. It is designed to handle large volumes of data and offers real-time search capabilities.
Key Concepts
1. Index
An index in Algolia is a collection of records. Each record is a JSON object representing an item you want to search.
2. Record
A record is a JSON object that contains data about a specific item. For example, a product in an e-commerce store.
3. Query
A query is a search request sent to Algolia to retrieve relevant records from an index based on user input.
Setup
To get started with Algolia, follow these steps:
- Sign up for an Algolia account.
- Create an application in the Algolia dashboard.
- Obtain your Application ID and Admin API Key from the dashboard.
- Install the Algolia client in your project:
npm install algoliasearch
Indexing Data
To index data, you need to create an index and add records to it. Here’s how to do it:
const algoliasearch = require('algoliasearch');
const client = algoliasearch('YourApplicationID', 'YourAdminAPIKey');
const index = client.initIndex('your_index_name');
// Sample records
const records = [
{ objectID: 1, name: 'Product 1', price: 10.99 },
{ objectID: 2, name: 'Product 2', price: 12.99 }
];
// Add records to the index
index.saveObjects(records).then(({ objectIDs }) => {
console.log(objectIDs);
});
Search Queries
To perform a search, you can use the following code:
index.search('Product 1').then(({ hits }) => {
console.log(hits);
});
Best Practices
- Always keep your index up to date with the latest records.
- Utilize Algolia's analytics to understand search behavior and improve relevance.
- Optimize your queries by using filters and facets to refine search results.
- Implement typo tolerance to enhance user experience.
