For a simple search, just type one or more words separated by spaces. Articles containing
any of the words will match, but articles containing the most words will appear first in
the results. An article's title, body, and keyword section are searched.
You may also use a more advanced search syntax, which also matches an article's
title, body, and keyword section. If any of the characters |, ^, or & appear
in your search query, the query will be parsed using the advanced syntax.
