When I go to the homepage of my group - http://groups.diigo.com/group/[groupname] - there is a search box at the top right with the text inside "Search in this group".

I recently added a link to the group with tags "Barcelona" and "food".

If I search for "Barcelona", I get a page saying:

Group items matching Barcelona in title, tags, annotations or url.
No result from this group.

However, on the right-hand side, there is a box with:

Related searches
See group items tagged Barcelona »

If I click the "See group items tagged Barcelona", I'm taken to a page with a heading "Group items tagged Barcelona", and the link I saved is listed there!

Why is the "Search in this group" function not working when entering tag names, when it clearly states that I am searching in "title, *tags*, annotations or url" ?

Thanks
Fab
