Include Author in search

Would it be possible to include authors as a search taxanomy?

e.g. “Tuula” would offer posts / pages written by Tuula, even if her name is not in the page content.

Example site. http://oppiva.omnia.fi/

Post that should appear in the search results: http://oppiva.omnia.fi/yrittajyysopinnot-motivoivat-tekemaan-innostumaan-ja-onnistumaan/
