The `search_volume` field specifies the axis-aligned bounding box that defines the boundaries of the search. The search sweeps along the axis defined by the `search_axis` field, layer by layer. For example, if `search_axis` = '-x', blocks with greater x values will be checked before blocks with lower x values. Each layer is searched from the bottom-left to the top-right before moving to the next layer along the axis. By default, only one valid position must be found, but this can be altered by specifying the `required_successes` field. If fewer than the required successes are found, no placement will occur.\nSucceeds if: The number of valid positions is equal to the value specified by `required_successes`.\nFails if: The number of valid positions is less than the value specified by `required_successes`.",
