Conditional Search

Hi, we have a database with projects and a database with wiki pages. We tag the wiki pages under a project to group them and so we can better manage access to pages and all.

Is there an easy and accessible way to immediately search wiki pages under such a project from the search bar? There is a search button on the item itself, but that one searches everything, while I would expect it to only search everything tagged with that item.

It would be real handy to have conditional search like this, as its quite common to group items for access control.
