因为开发环境的 Oracle 在 docker 容器中运行，并没有太多数据，手动添加公司时牵扯到 solr，于是我就清明节一下午时间就着手解决这个问题。下面我把这个解决办法记录在此，首先是一个额外问题的解决办法，如果遇到的话。 ORA-21561: 生成 OID 失败 (OCIError) 这个问题的解决办法如下：
It works at reach $ sudo echo -e "127.0.0.1\t`hostname`" >> /etc/hosts
正文开始，前面过程基本按照 Adding Sunspot search to Rails in 5 minutes or less 这个过程：
It works at reach $ ruby script/generate sunspot
/home/tux/.rvm/gems/ruby-1.8.7-p374@reach/gems/rails-2.1.1/lib/rails_generator/lookup.rb:211:Warning: Gem::SourceIndex#search support for Regexp patterns is deprecated, use #find_name
create config/sunspot.yml
注意和上述 wiki 对比，下面改 solr 为 rails 即可：
It works at reach $ cp `bundle show sunspot_rails`/lib/sunspot/rails/tasks.rb lib/tasks/sunspot.rake
并修改 lib/tasks/sunspot.rake 其中第 50 行代码，例如可改成这样：
all_files = Dir.glob("#{Rails.root}/#{File.join('app', 'models', '*.rb')}")
接下来启动 solr，建议先删除 ./solr 如果有的话：
It works at reach $ rake sunspot:solr:start
(in /var/www/reach)
Copied default schema.xml to /var/www/reach/solr/conf/schema.xml
Copied default solrconfig.xml to /var/www/reach/solr/conf
Copied default elevate.xml to /var/www/reach/solr/conf
Copied default spellings.txt to /var/www/reach/solr/conf
Copied default stopwords.txt to /var/www/reach/solr/conf
Copied default synonyms.txt to /var/www/reach/solr/conf
上述敲完又生成了 ./solr，再修改 /var/www/reach/solr/conf/schema.xml，在适当位置加上一行：
<dynamicField name="*_textp" stored="true" type="text" multiValued="true" indexed="true"/>
我第一次是把代码中所有 *_textp 给注掉了，所以改动比较多，不值得分享，现在我又发现了这个办法。
最后由于毕竟是开发环境，需要注掉几个文件，gird_file.rb 还有 aliyun 相关，注意，注释掉文件需要保留住 class SomeClass ... end，只注掉类里面的或者模块里面的东西即可。
最后可以把所有 solr 相关的 include ... if ENV["RAILS_ENV"] == 'production' 后面的条件去掉了，接下来可以成功 reindex 了。
It works at reach $ rake sunspot:solr:reindex
