Did they remove all Joomla! example content?

In Joomla! 1.0.x you can use the site's search functionality to find out if a site removed all example content. Or to show all content (partly) on a page... 

If the Search Mambots (nowadays, in 1.5 better known as Plugins) Joomla! 1.0.x are published, you can get a list of all published sections, categories, articles, weblinks, newsfeeds, and any other content (that is, if Search Mambots have been installed for that type of content) with one search!

Use a wildcard in the search field! Actually, because the search field requires a minimum of three characters, make that three wildcards:

Use as keyword: %%% (three percent signs in a row).

Technical background: The search field input is matched with the MySQL database, using a LIKE query which accepts '%' as wildcard character.

Note: This search method does not work in Joomla 1.5.x. It probably does not accept the % as wild card.
