Overview

Summary

Using a RegExpAnalyzer is a simple way to create a custom analyzer. If implemented in Ruby it would look like this;

class RegExpAnalyzer
def initialize(reg_exp, lower = true)
  @lower = lower
  @reg_exp = reg_exp
end

def token_stream(field, str)
  if @lower
    return LowerCaseFilter.new(RegExpTokenizer.new(str, reg_exp))
  else
    return RegExpTokenizer.new(str, reg_exp)
  end
end
end

Example

csv_analyzer = RegExpAnalyzer.new(/[^,]+/, false)
