Check if output of extensions has changed
At the moment indexed search checks only the last modification timestamp of the page itself and the content elements but does NOT know about the output of the plugins. I have a extension that renders a cached list of database entries. whenever someone adds an item to the list, the cache is emptied and the page is reloaded, the new output is there BUT indexed_search does NOT know about this change.
Something should be done to let indexes_seach know that the content has changed, otherwise the new content only gets indexed when the page properties or a content element changes.
