    Description

      LUCENE-1068 describes a bug in StandardTokenizer whereby a string like "www.apache.org." would be incorrectly tokenized as an acronym (note the dot at the end).

      Unfortunately, keeping the "backward compatibility" of a bug turns out to harm us.
      StandardTokenizer has a couple of ways to indicate "fix this bug", but unfortunately the default behaviour is still to be buggy.
      Most of the non-English analyzers provided in lucene-analyzers utilize the StandardTokenizer, and in v2.3.2 not one of these provides a way to get the non-buggy behaviour

      I refer to:

      • CzechAnalyzer
      • DutchAnalyzer
      • FrenchAnalyzer
      • GermanAnalyzer
      • GreekAnalyzer
      • ThaiAnalyzer
