search(permutation,fn,opt)

• permutation: use permute() to generate
• fn: function that receives qr and returns an object with 'score' value
• opt:
  • capacity: number of top-scoring items to retain
  • ecl: ECL level (0-3)
  • version: Version number (1-40)
  • batch:
    • start: index to start at
    • stride: amount to increment index byte
    • limit: number of items to iterate over
    • loop: number to loop around (usually permutation.total)
