Separate model noid concerns from controller noid concerns
Index title with `_sim` suffix in addition to the existing `_tesim` suffix
This enables an exact match search on title:
```ruby
GenericFile.where(desc_metadata__title_tesim: 'anoabo00-00001.jp2').map {|f| f.title.first }
\# => ["anoabo00-00001.jp2", "anoabo00-00002.jp2", "anoabo00-00003.jp2"]
GenericFile.where(desc_metadata__title_sim: 'anoabo00-00001.jp2').map {|f| f.title.first }
\# => ["anoabo00-00001.jp2"]
```
