+# Meilisearch {#module-services-meilisearch}
+
+Meilisearch is a lightweight, fast and powerful search engine. Think elastic search with a much smaller footprint.
+
+## Quickstart
+
+the minimum to start meilisearch is
+
+```nix
+services.meilisearch.enable = true;
+```
+
+this will start the http server included with meilisearch on port 7700.
+
+test with `curl -X GET 'http://localhost:7700/health'`
+
+## Usage
+
+you first need to add documents to an index before you can search for documents.
+
+### Add a documents to the `movies` index
+
+`curl -X POST 'http://127.0.0.1:7700/indexes/movies/documents' --data '[{"id": "123", "title": "Superman"}, {"id": 234, "title": "Batman"}]'`
+
+### Search documents in the `movies` index
+
+`curl 'http://127.0.0.1:7700/indexes/movies/search' --data '{ "q": "botman" }'` (note the typo is intentional and there to demonstrate the typo tolerant capabilities)
+
+## Defaults
+
+- The default nixos package doesn't come with the [dashboard](https://docs.meilisearch.com/learn/getting_started/quick_start.html#search), since the dashboard features makes some assets downloads at compile time.
+
+- Anonimized Analytics sent to meilisearch are disabled by default.
+
+- Default deployment is development mode. It doesn't require a secret master key. All routes are not protected and accessible.
+
+## Missing
+
+- the snapshot feature is not yet configurable from the module, it's just a matter of adding the relevant environment variables.
