implemented bug fix to handle multiple word keywords to all metrics
- multiple keywords treated like OR (inclusive)
- - eg keyword: sony playstation
- - keyword is present in url and title if: sony or playstation or sony playstation is present
- - keyword count updated to count sony, playstation, and sony playstation
- - - (double counting has been handled, program does not double count instance of sony playstation as both "sony" and "sony playstation"
