 When your application is deployed, we provide a search **ONLY** API key, scoped to your production index, so you don't have to worry disclosing it in the frontend.
 
+## Can I have multiple projects under the same Algolia application?
+
+We recommend having a single Algolia application per project. Please [apply](/apply) if you'd like to use DocSearch in an other project of yours.
+
+### Why ?
+
+The information of the initially applied project is used everywhere when we deploy your app:
+
+- The scope of your API keys
+- The name of your Algolia application/Crawler
+- The indices we generate
+- The allowed domains of your Crawler
+
+This allow us to easily scope issues when reaching out for support.

+## Search yield no results
+
+If your search does not yield any results, but there is no error in [your browser developer tools](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/What_are_browser_developer_tools), there might be an issue with your index.

+
+We provide [config templates](/docs/templates) for many website generators, but you can also use them as a base. To debug your selectors, we recommend using [the URL tester](/docs/manage-your-crawls/#url-tester).

+2. Your index settings are up to date (you'll see a banner in [the search preview](/docs/manage-your-crawls/#search-preview) if not)
+
+The Crawler only applies `index settings` at index creation index, to keep the Algolia dashboard as the source of truth. If you have drastically changed your config, or moved to a website generator, we recommend your to delete your index from the Algolia dashboard before starting a new crawl.

 - 🙁 If we need to render your website in the browser through JavaScript, it means that we'll have to crawl it through a much slower browser emulation. We highly recommend that you put in place server-side rendering for the useful textual content.
 
+## Process duration
+
+As stated in [the priority section](#priority), we receive a lot of requests every day. To ensure they all match [our checklist](#the-checklist), we manually review each of them, which means it can take a bit of time before you get an answer from us.
