Search by conten_type in rails?

I want to provide search functionality on the basis of spreadsheets, presentations, documents, images, videos etc ..

Are there any plugins or gems available for this type of functionality ? Any suggestions开发者_如何学C to provide this functionality ?

You can use paperclip gem to upload and store your files. It stores content_type automatically, so you`ll have a possibility to search/filter by content type etc.

If you want to provide indexed search functionality, why not integrate with Apache Solr engine?

You can use Sunspot for integrating with Apache Solr. Solr Cell which is integrated by default with latest Solr, allows you to index any type of Rich Text Documents.
