But the official website totally sucks, and looking for the right icon is a pain 🤮.
As a front end dev, I use icons a LOT and finding the right one is usually not a breeze.
So I have built a small web app to search MDI's icon. I have used Algolia to power the search and thanks to the open sourced collaborative list of meta tags for each MDI icons, the search will returns you related icons (eg : search for 'house' will return you 'home' icons as well).
Try it out : mdisearch.com
PS - It is open sourced, built with Vue and Vuetify.
