    MoinMoin - FullSearch Macro

    [[FullSearch]]
        displays a search dialog, as it always did.

    [[FullSearch()]]
        does the same as clicking on the page title, only that
        the result is embedded into the page. note the '()' after
        the macro name, which is an empty argument list.

    [[FullSearch(Help)]]
        embeds a search result into a page, as if you entered
        'Help' into the search box.

    The macro creates a page list without context or match info, just
    like PageList macro. It does not make sense to have context in non
    interactive search, and this kind of search is used usually for
    Category pages, where we don't care about the context.

    TODO: If we need to have context for some cases, either we add a context argument,
          or make another macro that uses context, which may be easier to use.
