Changing Bits: Lucene's FuzzyQuery is 100 times faster in 4.0 - 0 views

  • Lucene's FuzzyQuery is 100 times faster in 4.0
  • FuzzyQuery matches terms "close" to a specified base term
  • specify an allowed maximum edit distance, and any terms within that edit distance from the base term
  • ...3 more annotations...
  • FuzzyQuery is great for matching proper names
  • Prior to 4.0, FuzzyQuery took the simple yet horribly costly brute force approach: it visits every single unique term in the index, computes the edit distance for it, and accepts the term (and its documents) if the edit distance is low enough.
