for example:
i have a domain.com, but my company have a many different buisnesses: voip, aviation, gps-navigators etec...
it should be a god thing, if in the template codes will be <phpdig:directory='direction'>
for example <phpdig:directory='/voip'> or <phpdig:directory='/gps'>
and search must display only gps or voip matches. seach only in urls, witch begins from "domain.com/voip" or "domain.com/gps"
sorry for bad english
