Search is a Minecraft hack that highlights blocks of a specific type with rainbow-colored boxes. These boxes can be seen through walls.

Search is similar to X-Ray, but there are two main differences:

1. Search can only reveal one type of block at a time, X-Ray can reveal multiple types of blocks simultaneously.
2. Search works by highlighting blocks, X-Ray works by hiding blocks.

The second difference also allows Search to work with mods like OptiFine and Sodium, which alter Minecraft's rendering code in such a way that X-Ray can no longer hide blocks.

The “Block” setting determines the type of block that Search will highlight. It can be set to almost any block that exists in the game, including custom blocks added by mods. It cannot be set to air blocks, as that would cause a lot of lag and have no practical use.

The “Area” setting determines the area around the player in which Search will search for blocks. The area is measured in chunks, not blocks. The default value of 11×11 chunks is equivalent to a 176×176 block area. Setting this to a higher value will cause Search to search for blocks in a larger area, but it will also cause a significant decrease in performance and increase in CPU usage.

The “Limit” setting determines the maximum number of blocks to display. The default value of 10⁴ (or 10,000) means that Search will only highlight up to 10,000 blocks at a time, even if there are more blocks of the selected type nearby. Setting this to a higher value will cause Search to highlight more blocks at once, but it can also negatively affect performance.

Values are displayed as regular numbers, but saved as orders of magnitude (e.g. the default 10,000 blocks value is saved as 4). This becomes visible when shift-clicking on the “Limit” slider to manually enter a value: Instead of entering the desired number of blocks directly, the user must enter the desired order of magnitude.
