Question

我正在处理的Rails项目正在使用Solr搜索，但在输入某些数据时，搜索功能不会返回结果。

如果传递了电子邮件，guid（全球唯一标识符），电话号码或客户信用卡的最后4个，搜索功能应返回结果。目前它只适用于电子邮件或guid。

我甚至不知道从哪里开始排除故障，因为每当我搜索Solr搜索时，我只返回项目未使用的太阳黑子宝石的结果。

应用程序控制器中包含的Solr搜索模块如下所示：

module SolrSearch
  def solr_query(query_string)
    query_string << "&fq=publisher_name:#{UMS[:publisher_name]}"
    uri = SOLR_URL + "/select/?version=2.2&start=0&rows=100&indent=on&qt=dismax&wt=json&fl=id,guid,email,user_name,publisher_name,csg_id,state,created_at&q=#{query_string.downcase.strip}"
    response = Curl::Easy.http_get(URI.escape(uri))
    result = JSON.parse(response.body_str)
    return result
  end
end

如果我没有在搜索字段中输入任何内容，我会使用guid，user_name，email，publisher_name，state和created_at返回一组用户。

我的gemfile看起来像：

显然我已经尝试将phone_number添加到URI字符串中，但这不起作用。

我该如何开始对此进行故障排除？

根据Tinman的建议，我尝试使用URI类对查询字符串进行编码。我做了：

module SolrSearch
  require 'uri'

  def solr_query(query_string)
    uri = URI.parse(SOLR_ICEBOX_URL)
    uri.query = URI.encode_www_form(
      'fq' => "publisher_name:#{UMS[:publisher_name]}",
      'version' => 2.2,
      'start' => 0,
      'rows' => 100,
      'indent' => 'on',
      'qt' => 'dismax',
      'wt' => 'json',
      'fl' => 'id,guid,email,user_name,publisher_name,csg_id,state,created_at',
      'q' => query_string.downcase.strip
    )
    result = JSON.parse(response.body)
  end
end

至于构建URL，不要使用字符串连接或插值，除非你绝对确定结果字符串是否正确编码。

相反，我建议利用内置的URI类，它将为您解决这个问题：

require 'uri'

SOLR_URL = 'http://somehost.com/select/'
UMS = {publisher_name: 'some company'}
query_string = 'foo bar'

uri = URI.parse(SOLR_URL)
uri.query = URI.encode_www_form(
  'fq' => "publisher_name:#{UMS[:publisher_name]}",
  'version' => 2.2,
  'start' => 0,
  'rows' => 100,
  'indent' => 'on',
  'qt' => 'dismax',
  'wt' => 'json',
  'fl' => 'id,guid,email,user_name,publisher_name,csg_id,state,created_at',
  'q' => query_string.downcase.strip
)

运行会导致uri看起来像：

uri.to_s
# => "http://somehost.com/select/?fq=publisher_name%3Asome+company&version=2.2&start=0&rows=100&indent=on&qt=dismax&wt=json&fl=id%2Cguid%2Cemail%2Cuser_name%2Cpublisher_name%2Ccsg_id%2Cstate%2Ccreated_at&q=foo+bar"
