Params

Params are used in most commands to define the search parameters. For console use, every time world must be specified (direct or using last) and area and selection aren’t available. You can escape a word which would normally be caught as keyword using double quotes ("), e.g:
/lb world "world"

Location

• area <radius>

  To only search for near block changes. The area has a square shape. If no radius is specified, the default radius will be used (lookup.defaultDist). A radius of 0 stands for a single block and is used for tool queries.

• sel | selection

  To search only inside the current WorldEdit selection. Works only for cuboid selections.

• loc [x]:[y]:[z] | location [x]:[y]:[z] (v1.51+)

  Specify a single block.
  You can use : or to seperate, like loc 45 -12 64 or loc -123:265:70
  

• world [worldname]

  Selects the world. Required for console commands. Allows to look up in a specific world.
  Default is the current world.

Type

What to search for. Can not be combined.

• all

  Looks up all blocks (including actions) and chestaccess

• kills

  Looks up only kills assuming it is enabled in the config

  • killer [name1] {<name2>}, victim [name1] {<name2>}

  • search, match

    Search the chat history for some words. Refers to http://dev.mysql.com/doc/refman/5.0/en/fulltext-boolean.html.

    Example:
    /lb chat player diddiz search home
    or
    /lb chat player diddiz search tree home
    Will search for all messages by player diddiz containing the words tree OR home.
    /lb chat player diddiz search +tree +home
    Same as previous, but both words have to appear.
    /lb chat player diddiz search tree -home
    Find all with tree but without home.
