The Complete Opensolr Platform Guide

Managed Solr Hosting

Opensolr is a fully managed Apache Solr hosting platform. You get production-grade Solr clusters without managing servers, JVMs, or replication — we handle all of that.

Getting Started — Create Your First Index

1. Create your account

Head to opensolr.com and click Sign Up. Enter your email, choose a password, and confirm via the activation email. Once logged in, you land on your Dashboard — the central hub for indexes, clusters, billing, team members, and API keys.

2. Open the Control Panel and click "Add New"

Click your username in the top-right corner, select Control Panel, then open My Indexes and click Add New.

3. Choose your region and Solr version

Use the filter dropdowns to select a Region, Solr Version, and optionally a Country. Click the cluster card that matches your needs.

4. Name your index and create it

Give your index a meaningful name (e.g. my_website, product_search) or keep the auto-generated ID. Click Add Index — your index is provisioned in seconds with connection details, hostname, port, and credentials ready to use.

5. Upload your configuration

Click your index name to enter its Index Control Panel, then go to Configuration. Edit config files live in the browser (schema.xml, solrconfig.xml, synonyms, stopwords) or upload a ready-made config zip for your CMS. Your index is now ready to receive data.

See Solr Configuration Files Dependency Flow for details on how config files work together.

The Opensolr Control Panel

A single web-based dashboard for managing every aspect of your Solr indexes — from live analytics and query monitoring to configuration, security, backups, and index tools.

Connect Your Application

Opensolr Web Crawler

Don't have an app backend or CMS? The Opensolr Web Crawler crawls any website and builds a fully indexed, searchable site — no code, no plugins, no infrastructure to manage.

App Server Management

Beyond Solr hosting, Opensolr manages your entire application stack — Drupal, Laravel, WordPress, or any framework running on your own servers or ours.

Drupal Modules — Opensolr Turbo Indexer

Opensolr actively contributes to the Drupal ecosystem. Our flagship Drupal module is the Opensolr Turbo Indexer — a Drush-based parallel indexing engine that dramatically speeds up Solr indexing for large Drupal sites.

We also maintain the Search API Opensolr connector module, which simplifies connecting Drupal's Search API to any Opensolr-hosted index.

AI-Powered Search

Opensolr offers built-in AI search capabilities that go beyond traditional keyword matching.

REST API — Automate Everything

Every operation in the Opensolr Control Panel is available through the REST API. Automate index provisioning, config management, security, backups, crawling, and monitoring programmatically.

Quick API Examples

Once your index is live, interact with it directly via HTTP. Replace USER:PASS with your index credentials and CLUSTER.opensolr.com with your cluster hostname.

Search:

curl -u USER:PASS "https://CLUSTER.opensolr.com/solr/INDEX_NAME/select?q=laptop&rows=10&wt=json"

Index a document:

curl -u USER:PASS "https://CLUSTER.opensolr.com/solr/INDEX_NAME/update?commit=true" \
  -H "Content-Type: application/json" \
  -d '[{"id":"1","title":"My First Document","content":"Hello Solr!"}]'

PHP:

$url = 'https://CLUSTER.opensolr.com/solr/INDEX_NAME/select?q=laptop&wt=json';
$context = stream_context_create(['http' => [
    'header' => 'Authorization: Basic ' . base64_encode('USER:PASS')
]]);
$response = file_get_contents($url, false, $context);
$data = json_decode($response, true);
print_r($data['response']['docs']);

JavaScript:

const response = await fetch(
  'https://CLUSTER.opensolr.com/solr/INDEX_NAME/select?q=laptop&wt=json',
  { headers: { 'Authorization': 'Basic ' + btoa('USER:PASS') } }
);
const data = await response.json();
console.log(data.response.docs);
