The Windows Shell supports several search handler that allow users to locate
files, printers etc. The default Windows search handler is not able to search in
OOo files, but it's possible to create a custom search handler for OOo files
that may be registered with the Windows Shell. 
There are virtually no limits in what the user may search for, e.g. a single
word, a text phrase, a specific author etc. 
A user has two ways to select a search engine. The first way is from the Start
menu. With systems earlier than Microsoft® Windows® 2000, selecting the Find
command on the Start menu displays a submenu of the available search engines.
With Windows (R) 2000 and later, the Start menu's Find command is renamed Search. 
A user can also launch a search handler from the Windows (R) Explorer. 
On systems earlier than Windows (R) 2000, they click the Find command on the
Tools menu to display essentially the same menu as the one associated with the
Start menu. However, Windows Explorer (R) for Windows (R) 2000 and later handles
search engines in a very different way. Instead of handling search engines as a
submenu of the Tools menu, there is now a Search button on the toolbar. Clicking
this button opens the Explorer bar's Search pane. An application may create and
register its own search pane based on DHTML that will be launched by the Windows
Explorer for application specific file types.
