Full-Text Search for saved websites

I like the idea to have a full-text search over all links with its content.

Idea for the implementation

• a cronjob graps the main content of the site. Maybe with this package
• the HTML and/or the plain text of the article will be saved in the database
• in the first step a search can be implemented with MySQL full-text search
• in the future can be redis search an option for a better search experience

What do you thing about this feature? Could this feature relevant for this project?
