Class: Ferret::Analysis::AsciiWhiteSpaceAnalyzer

Summary

The AsciiWhiteSpaceAnalyzer recognizes tokens as maximal strings of non-whitespace characters. If implemented in Ruby the AsciiWhiteSpaceAnalyzer would look like; 

  class AsciiWhiteSpaceAnalyzer
    def initialize(lower = true)
      @lower = lower
    end

    def token_stream(field, str)
      if @lower
        return AsciiLowerCaseFilter.new(AsciiWhiteSpaceTokenizer.new(str))
      else
        return AsciiWhiteSpaceTokenizer.new(str)
      end
    end
  end

As you can see it makes use of the AsciiWhiteSpaceTokenizer. You should use WhiteSpaceAnalyzer if you want to recognize multibyte encodings such as "UTF-8".

Public Class Methods

AsciiWhiteSpaceAnalyzer.new(lower = false) → analyzer

Create a new AsciiWhiteSpaceAnalyzer which downcases tokens by default but can optionally leave case as is. Lowercasing will only be done to ASCII characters.

lower:set to false if you don‘t want the field‘s tokens to be downcased
