Allow the download of the manga database in order to do the searches locally

[panzerkampfwagyu]

I often heard that a lot of filtering was hard to implement for the site due to it having a lot of server load.
So, I was wondering, would it be possible to make it that users can download, for example, the database of their own library and do the filtering/sorting locally and up that result instead? Or use ways to process the entire thing on the user device.
Should take the load off the servers and allow for more complex database manipulations.
