Let's ask the GNOME Do and Deskbar people about this? Would a system
like Tracker help the projects?

I'm afraid that just like Lennart you aren't trying to parse it. And
therefor is Jamie right that it's not productive to go on about this.

To end it the way the person you are copycatting ends his sentences:

Free text search is just one possible way to get such a list. The
relationships between resources is going to be the most common way to
access related resources.

You wont necessarily search, you will select "Joe" in a list and then
you'll provide what it is about Joe that you want (E-mails, Friends,
Photos, Locations, Documents, Chat logs).

That's not the same as typing in a search term. Although free text
search can be utilized to further fine tune a result-set. But not
usually as the primary or only criteria entered by the user.

Note that it's rare that you have zero context about what the user
expects to see next. I guess the only use-case for that is google-com.

Which is a nice use-case, but most definitely not the only one. And even
for google-com is the context: I want web resources that aren't private
but will interest me, if I'm logged in. That's not zero-context.

Thanks for your opinion.
