To enable Crelate's External Resume Search, you'll want to navigate to Settings>>External Resume Search.
Next, you'll be prompted to select a plan. The pricing for this feature is per resume. You may pre-pay for a defined package of your choice.
You may then search organically through Crelate using Boolean logic.
Once, in search, you'll notice an "External Resumes" option which will display those resumes sourced from your external search. You'll also notice salary, radius, and "resume last updated" filters over to the right hand side of your screen.
To unlock a resume, double click that individual's profile. Next, you'll be prompted to preview that document. You'll notice your 'Credits Remaining' in the lower left. This will let you know how many resume unlocks you have remaining on your current plan. In the lower right of your screen, you may then 'unlock' that resume.
After selecting unlock, you'll be prompted to confirm.
You will then be brought to that contact's record and may interact with that profile as you would any other Crelate contact.
