How to build up a centralised search in vb for calendar/forum/internet

[hr66]

Hi,
vbulltin works perfect.
The only real point which is not satisfying is the search.
We have to search in the calendar, in the forum, in the web, in the links directory,...
Is it possible to make one formular, which is posting the search word to the search of the forum, the search of the calendar, the search in the internet (if it is installed), ...
... and to get the results back grouped by this different areas.

An example:
Searchword: car
Answer
x answers in the forum
x answers in the calendar
x answers in the www
x answers in the links directory

And with a cklick on the are we will see the search results. Maybe grouped on a panel.
Who has ideas? Can we develope something together to save costs?
Best regards
hr
