Introduction

Apache Solr and Elasticsearch are both incredibly powerful open-source search engines that can deliver lightning-fast search results for developers who want to provide users with an optimized search experience. Both of these tools can perform a wide range of search-related functions, including text searches, suggestions, spellchecking, and more. In this post, we will take a closer look at the differences between Apache Solr and Elasticsearch, and which one may be better suited to your specific needs.

Apache Solr vs Elasticsearch: Which One is Better?

Both Apache Solr and Elasticsearch can deliver impressive search engine capabilities. Here are a few key differences between the two:

Data Handling

Apache Solr is often preferred for its data handling capabilities. It is particularly well-suited for handling complex, structured data. From a data handling perspective, Solr offers a clear advantage over Elasticsearch.

Scalability

When it comes to scalability, Elasticsearch is the clear winner. Elasticsearch is built with distributed architecture in mind, allowing it to scale to even the largest use-cases without breaking a sweat. If you need to handle a high volume of searches and data, Elasticsearch is a better choice.

Ease of Use

Elasticsearch is generally considered to be easier to use than Apache Solr. Developers often cite Elasticsearch’s simple RESTful API as a key advantage over Solr. Additionally, Elasticsearch is built with a flexible data model, making it easier to work with for those without an in-depth understanding of search engine architecture.

Community Support

Both Solr and Elasticsearch have large, active communities that provide support and contribute to the development of the software. However, Elasticsearch’s community is currently more active and growing at a faster rate than Solr’s.

Example PHP Client Code for Elasticsearch

Here is an example of how you might use Elasticsearch in a PHP environment. This code connects to an Elasticsearch cluster and performs a search query:


// Connect to Elasticsearch
$client = Elasticsearch\ClientBuilder::create()->build();

// Define search query
$params = [
    'index' => 'my_index',
    'body' => [
        'query' => [
            'match' => [
                'my_field' => 'search_term'
            ]
        ]
    ]
];

// Send query and get results
$response = $client->search($params);
$results = $response['hits']['hits'];
