+## Search
+
+Built in integration with the excellent [FlexSearch.js](https://github.com/nextapps-de/flexsearch). A fast full text search that reads a JSON file created by Hugo to index and search the site.
+
+Here is the three steps needed to create a search page.
+
+1. Add a new output format in your configuration file.
+    ```
+    outputFormats:
+      SearchIndex:
+        mediaType: "application/json"
+        baseName: "searchindex"
+        isPlainText: true
+        notAlternative: true
+    ```
+2. Add the new output format to output setting for "home".
+    ```
+    outputs:
+      home: ["HTML", "SearchIndex", "[other formats you need]"]
+    ```
+3. Add the shortcode `{{< search >}}` to a page. Also set `searchform: true` in the front matter for that page so the search and flexsearch js files gets loaded.
+
+Your search page will now have a search field where all the posts of the site can be searched.
+
+The only setting is "searchLimit" that defaults to 20.
