This fantastic app will let you install several FoxTrot Search index files from your Mac into your iPad or iPhone via iTunes, then search through them off-line and display the text of your Mac documents from anywhere without connecting back to your Mac.
It equates to having a compressed text-only archive of your entire e-mail, calendar, address book, PDF, word process from which you can search through the essentials from anywhere.
Note: this app is to be used as a companion to FoxTrot Professional Search for Mac, or FoxTrot Personal Search for Mac.
