因為開發環境的 Oracle 在 docker 容器中運行，并沒有太多數據，手動添加公司時牽扯到 solr，于是我就清明節一下午時間就著手解決這個問題。下面我把這個解決辦法記錄在此，首先是一個額外問題的解決辦法，如果遇到的話。 ORA-21561: 生成 OID 失敗 (OCIError) 這個問題的解決辦法如下：
It works at reach $ sudo echo -e "127.0.0.1\t`hostname`" >> /etc/hosts
正文開始，前面過程基本按照 Adding Sunspot search to Rails in 5 minutes or less 這個過程：
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 對比，下面改 solr 為 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 行代碼，例如可改成這樣：
all_files = Dir.glob("#{Rails.root}/#{File.join('app', 'models', '*.rb')}")
接下來啟動 solr，建議先刪除 ./solr 如果有的話：
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，在適當位置加上一行：
<dynamicField name="*_textp" stored="true" type="text" multiValued="true" indexed="true"/>
我第一次是把代碼中所有 *_textp 給注掉了，所以改動比較多，不值得分享，現在我又發現了這個辦法。
最后由于畢竟是開發環境，需要注掉幾個文件，gird_file.rb 還有 aliyun 相關，注意，注釋掉文件需要保留住 class SomeClass ... end，只注掉類里面的或者模塊里面的東西即可。
最后可以把所有 solr 相關的 include ... if ENV["RAILS_ENV"] == 'production' 后面的條件去掉了，接下來可以成功 reindex 了。
It works at reach $ rake sunspot:solr:reindex
