The main googleajaxsearch module allows you to add inline searches over a number of Google services (Web Search, Local Search, Video Search, Blog Search, and News Search).
FireStats is a web statistics system. This module allow FireStats to monitor access to your Drupal site. A live demo of FireStats is available here. Please report Firestats integration module's problems in the project issue tracker and the statistics system's problems to http://firestats.cc/
Visibility API (Optional):
Firestats module is integrated with Visibility API module to set stats collection from specific parts of the website only; just like the block visibility setup.
The directory module presents a very simple and lightweight hierarchical 'directory-like' view (conceptually similar to DMOZ, Yahoo, etc.) of nodes that have been assigned to one or more designated taxonomy 'vocabularies' (depending on module configuration). This allows users to drill down on selected content on your Drupal site.
If you have a site with taxonomies already in place, and/or you are not using the category module, this module may be a simpler approach to hierarchical navigation - just drop it in, configure, and go.
This module allows users to type Vietnamese characters while creating or editing Drupal nodes or setting the site name or menu names or taxonomy names, etc. The module creates a block, in which there are options of several Vietnamese input method. This block should be automatically turned on. It is set by default to appear only in the editing mode, i.e. when you add a node, edit a node, or edit something in admin panel. To modify this configuration, go to admin/block and change the block's configuration.
The Bookmark Us Module allows visitors to quickly and easily bookmark your site, and the current page. Very flexible. Works with IE, Opera, Firefox, Netscape, and other Gecko-based browsers.
Update: For Drupal 8 please use the redirect module. This project is deprecated for D8
What?
GlobalRedirect is a simple module which…
Checks the current URL for an alias and does a 301 redirect to it if it is not being used.
Checks the current URL for a trailing slash, removes it if present and repeats check 1 with the new request.
Checks if the current URL is the same as the site_frontpage and redirects to the frontpage if there is a match.
Checks if the Clean URLs feature is enabled and then checks the current URL is being accessed using the clean method rather than the 'unclean' method.
Checks access to the URL. If the user does not have access to the path, then no redirects are done. This helps avoid exposing private aliased node's.
Make sure the case of the URL being accessed is the same as the one set by the author/administrator. For example, if you set the alias "articles/cake-making" to node/123, then the user can access the alias with any combination of case.
Most of the above options are configurable in the settings page. In Drupal 5 you can access this after enabling the globalredirect_admin module. In Drupal 6, the settings page is bundled into the module.
