With SkillBot, you can search the text of thousands of resumes in a couple of minutes. But SkillBot does not have the power and depth of human intelligence. SkillBot does not understand and interpret the resumes for you. This is to point out that it is up to you to come up with queries that will find the resumes you are after. You have to imagine what the person you are looking for would write in their resume.
