All too often Yahoo is neglected by recruiters when sourcing directly and it really shouldn't be as it is one of the biggest indexes that exists on the planet and spider and indexs differently to that of Google and Live.
Recently, Yahoo introduced it's "region" command. The syntax when searching for candidates would look a little like this
region:"continent" intitle:resume "keyword"
For example, if you are looking for resumes of a Auditor in Europe, your search string will be
region:europe intitle:resume auditor -sample -apply -jobs
