You can enter several search terms, both those that are to be included in the page (+ in front of the word) as well as those that should not appear on the page (- in front of word).
You can also create combined search terms by using quote marks around two or more words.

Example: +"Jón Jónsson" -"Jóna Jónsdóttir"
