iBooks - slow when searching large pdf's

I am trying to search a 1300 page document though.

Takes 5 minutes or more on an iP4. My mac is pretty instantaneous (but that's Apples to Oranges of course).

I need a PDF App that's faster at searching. There's just too damn many in the app store to chose from.

Any suggestions?

Also, is there an app that lets me organize PDF's by putting them in folders or something? Rather than having them scattered randomly on the iBooks shelves.

 

I know! It's like I'm talking to myself.
