solr,太阳黑子,不良要求,非法性格

Question

我正在向我的项目介绍太阳黑子搜索.我只是通过名字字段搜索得到了一个POC.当我介绍说明字段并重新索引销售时,我收到以下错误.

我该怎么做才能让solr忽略它或清理数据,以便卖出来处理它.

将以下内容放在初始化程序中以自动清除任何UTF8控制字符的太阳黑子调用:

# config/initializers/sunspot.rb
module Sunspot
  # 
  # DataExtractors present an internal API for the indexer to use to extract
  # field values from models for indexing. They must implement the #value_for
  # method, which takes an object and returns the value extracted from it.
  #
  module DataExtractor #:nodoc: all
    # 
    # AttributeExtractors extract data by simply calling a method on the block.
    #
    class AttributeExtractor
      def initialize(attribute_name)
        @attribute_name = attribute_name
      end

      def value_for(object)
        Filter.new( object.send(@attribute_name) ).value
      end
    end

    # 
    # BlockExtractors extract data by evaluating a block in the context of the
    # object instance, or if the block takes an argument, by passing the object
    # as the argument to the block. Either way, the return value of the block is
    # the value returned by the extractor.
    #
    class BlockExtractor
      def initialize(&block)
        @block = block
      end

      def value_for(object)
        Filter.new( Util.instance_eval_or_call(object, &@block) ).value
      end
    end

    # 
    # Constant data extractors simply return the same value for every object.
    #
    class Constant
      def initialize(value)
        @value = value

      def value_for(object)

        return value unless value.is_a? String

        value.chars.inject("") do |str, char|
          unless char.ascii_only? and (char.ord < 32 or char.ord == 127)
