+
+Search replaces the native Flarum search functionality which relies on MySQL badly performing
+fulltext search with one that is completely relying on the proven elasticsearch engine.
+
+## Features
+
+- Sync discussions to elastic search using your queue, unobtrusively for the user.
+- Reduces search loading times to well below 400ms (local tests with 50.000 discussion **260ms**)
+- Uses Flarum's group permissions and tags system.
+- Compatible with Friends of Flarum Byōbu.
+
+## Premium
+
+Managed Flarum communities that we host on our platform ([blomstra](https://blomstra.net)) will have access to all premium extensions we publish without additional cost.
+
+Alternative you can see our plans on [extiverse](https://extiverse.com/extension/blomstra/search). After completing your order, check your active [subscriptions](https://extiverse.com/premium/subscriptions) and follow the provided instructions. Then install using:
+
+```bash
+composer require blomstra/search:*
+```
+
+Enable the extension inside the admin area and continue below with the Set up.
+
+### Set up
+
+You will need a running Elasticsearch instance. Many providers offer these as a managed service, including
+[Stack Hero](https://www.stackhero.io/en/services/Elasticsearch/benefits).
+
+Modify your `config.php` by adding an entry `elastic` like so:
+
+```php
+return [
+    'elastic' => [
+        'endpoint' => 'https://somedomain:9200',
+        'username' => '<username>',
+        'password' => '<password>'
+    ]
+];
+```
+
+Or using an api token:
+
+```php
+return [
+    'elastic' => [
+        'endpoint' => 'https://somedomain:9200',
+        'api-id' => '<id>',
+        'api-key' => '<key>'
+    ]
+];
+```
+
+Enable the extension in your admin area. Now to seed your existing discussions use the following command:
+
+```
+php flarum blomstra:search:documents:rebuild
+```
+
+All mutations to discussions are automatically added and removed from the elasticsearch index.
+
