How do I rank the importance of my keywords?

Keywords can be Required ("AND"), Optional ("OR"), and Excluded ("NOT"). To see these options, click "Switch to Basic" below the keywords field and type your terms (or drag and drop suggested terms) into the appropriate rows.

On the Advanced view, you can build a Boolean search string.

The Suggested Keywords feature learns word associations over time based on the searching habits of your coworkers. This allows the more novice recruiters at your company to develop and strengthen their searching skills by learning from those with more experience.
