This is just a matter of opinion: I wonder about the drain on resources having PB4 index its files and attachments at the same time that a desktop index engine such as WDS 3.01, Google desktop, or Copernic is also trying to index. And, what happens when the desktop search engine starts trying to index the index of PB4?
I'm surely not a programmer but logic just seems to suggest that if there are very capable desktop search engines, what is the necessity of having a search engine just for PB4? Won't any of the above-mentioned search engines also is index PB4 thoughts, notes (I know they will index attachments)?
PB4 users running Windows XP have the option of not deploying any of the search engines. But this will not be possible with WindowsVista as it has the search engine embedded in the operating system (and is obviously the source of a festering-possible- lawsuit between Google and Microsoft).
