+## Search not working ?
+
+If you are using a CDN to server assets from a different domain, search would break
+
+Why? Take a look at [fastsearch.js#L35](https://github.com/adityatelange/hugo-PaperMod/blob/fb4988cfb6d0d6e4e489f17d89f0fa618def3396/assets/js/fastsearch.js#L35).
+
+We fetch the `index.json` (where the search function looks for the keywords typed) one level up of the website `search.min.js` is hosted on.
+
+We have used this insted of assigning `baseURL` so as to work with multilingual websites ex. `example.com/fr/` and websites being placed under a subdirectory ex. `example.com/blog/`.
+
+To fix for _single_ language websites hosting assets from CDN, this you may [override](#override-theme-template) [fastsearch.js#L35](https://github.com/adityatelange/hugo-PaperMod/blob/fb4988cfb6d0d6e4e489f17d89f0fa618def3396/assets/js/fastsearch.js#L35) and placing appropriate URL as in
+
+```js
+xhr.open("GET", "https://example.com/index.json");
+```
