Laravel Elasticsearch – Elasticsearch integration

Integrating Elasticsearch with your Laravel application can enhance search capabilities significantly.

Step 1: Install Elasticsearch

If you haven’t installed Elasticsearch yet, you can do so by following the instructions on the official Elasticsearch website. Make sure it’s running on your local machine or server.

Step 2: Install the Elasticsearch PHP Client

You can install the Elasticsearch PHP client via Composer. Run the following command in your terminal:

Step 3: Configure Elasticsearch in Laravel

To connect Laravel with Elasticsearch, you should create a configuration file. You can do this by creating a new config file:

1. Create a configuration file at config/elasticsearch.php:

2. Add the Elasticsearch host configuration in your .env file:

Step 4: Create a Service Provider

Create a service provider to encapsulate Elasticsearch functionality. You can do this with the following command:

In the ElasticsearchServiceProvider, set up the Elasticsearch client:

Step 5: Register the Service Provider

Next, you need to register your new service provider. Open config/app.php and add your ElasticsearchServiceProvider to the providers array:

Step 6: Create an Index

Now, create an index in Elasticsearch where you will store your documents. You can do this via a controller or directly using artisan commands.

Here’s an example of how to create an index using a controller:

1. Create a controller with the command:

2. In the ElasticsearchController, add methods to create an index:

Step 7: Define Routes

Define routes to access the Elasticsearch functionality in routes/web.php:

Step 8: Testing the Index Creation

1. Start your Laravel development server:

2. Visit http://localhost:8000/create-index in your browser. You should see a JSON response indicating the success of the index creation.

Step 9: Indexing Documents

Now, you can index documents in Elasticsearch. Update your ElasticsearchController to include a method for indexing documents:

Step 10: Define a Route for Indexing Documents

Add a route to handle document indexing in routes/web.php:

Step 11: Testing Document Indexing

Visit http://localhost:8000/index-document in your browser to index a sample document. You should see a JSON response indicating the success of the indexing.

Step 12: Searching Documents

You can also search for documents in your Elasticsearch index. Update your ElasticsearchController to include a search method:

Step 13: Define a Route for Searching Documents

Add a route for searching in routes/web.php:

Step 14: Testing Document Search

To search for documents, you can access the search route with a query parameter, for example:
