Koan Image Repository - Search Help

The database is indexed by pyramid. This means that the request you enter will be compared against each and every pyramid in each and every koan. The search syntax used is a subset of CQL. The list of categories and valid descriptors are as follows:

• Color: Red Green Blue Yellow Orange Purple Cyan Clear Black White
• Size: Small Medium Large
• Position: Grounded Stacked Floating
• Orientation: Upright Flat Weird

There are also 2 special categories:

• Num: The number of pyramids in the koan
• Pips: The total pip-count of the koan

The following relational operators are available: <, >, <=, >=, =, <>, and, or, not ¹⁾ You can also use parentheses () to group queries together.

• upright
  • Returns all koans cosisting of at least 1 upright pyramid.
• upright and color<>green
  • Returns all koans consisting of at least 1 upright pyramid and no green pyramids whatsoever.
• num>2 and (blue or purple) orientation<>weird
  • Would first select all koans that consist of 3+ pyramids. It would then weed out any of those koans that do not contain at least 1 blue or 1 purple pyramid. It would then remove all koans consisting of any weird pyramids.
• color <> (orange and purple and cyan and black and clear and white)
  • Returns all koans that have only red, yellow, blue, and green pieces.
