hmmm. google indexes more filetypes:
“Google has quietly extended the scope of its web index, for the first time including a number of file formats that are all but ignored by other search engines. These file formats make up a small but important part of the Invisible web, and Google’s effort to make them searchable is a noteworthy advance in search engine technology.
The new file types indexed by Google include Microsoft Word, Excel and PowerPoint formats, as well as Rich Text Format and PostScript files, according to Google spokesperson Cindy McCaffrey.”
certainly a necessary as google tries to generate revenue from hosted search capabilities for “enteprise” customers.
