An example of a successful search, showing results for 4 containers including a named chest and the player's specific ender chest. Shaders: Iris 1.20-1.6.4/Sodium 1.20-0.4.10 with BSL 8.2.04
Example of a search purely for the Efficiency V enchantment - you can do this in your favourite recipe viewer by searching for the given enchanted book, and by holding shift you can filter further for a level. Also supports specific potion effects!
An example of searching within nested containers; currently this supports shulker boxes and bundles.
Where Is It can function purely server-side; players including vanilla clients can use the `/whereis` command (default, changeable) to search by most criteria.
