The MFP doesn't do OCR/Searchable.
In the Windows world there are hundreds of free TWAIN Applications that can do it with this device, but Macs are a whole different story.
As of today, you would need to download the TWAIN scan driver from Xerox.com that is compatible with OSX 10.9.
Then you would need to disable SIP on OSX 10.11 just to run the TWAIN installer package.Then re-enable SIP.
Then it *should* install and *might* actually work.
And at that point you would then need to find a Mac software solution that does on the fly OCR from a TWAIN source that still works in 10.11 (Apple went above and beyond with 10.11 in blocking bi-directional communication with devices through new security implementations)
In short:
The MFP can't, but third party might, assuming you can workaround SIP
