As a newbie, I'm not sure what behaviour I should expect when there's a field at the bottom of the window that says "search", as opposed to the link at the bottom of a wiki page that says "search".
If I stop and think about it these, the search field is beside the count of pages in the neighbourhood. However, my newbie sense has become accustomed to the idea of Google Search, which might be different from the older idea of Yahoo Search that went into categories (i.e. YAHOO as a backronym for Yet Another Hierarchically Organized Oracle").
For a newbie, is "search" the right term for either the window search field, or the page bottom link?
