+Gutenberg can build a search index from the sections and pages content to
+be used by a JavaScript library: [elasticlunr](http://elasticlunr.com/). 
+
+To enable it, you only need to set `build_search_index = true` in your `config.toml` and Gutenberg will
+generate an index for the `default_language` set for all pages not excluded from the search index.
+
+It is very important to set the `default_language` in your `config.toml` if you are writing a site not in 
+English: the index building pipelines are very different depending on the language.
+
+After `gutenberg build` or `gutenberg serve`, you should see two files in your static directory:
+
+- `search_index.${default_language}.js`: so `search_index.en.js` for a default setup
+- `elasticlunr.min.js`
+
+As each site will be different, Gutenberg makes no assumptions about how your search and doesn't provide
+the JavaScript/CSS code to do an actual search and display results. You can however look at how this very site
+is implementing it to have an idea: [search.js](https://github.com/Keats/gutenberg/tree/master/docs/static/search.js).
