I think the livesearch macro would be a good candidate to upgrade it with some CQL magic the same way the content-by-label and content-by-user macros already were changed.

Hey natalie.swallow this is global search.

Hi Sherif, is this just for the global search or the livesearch macro as well?

Hi All,
Thank you for your patience with this issue. We are pleased to announce that ability to filter search results for multiple spaces is coming shortly to Confluence 5.9 (due in a few weeks) and is already shipped in Confluence Cloud.

Hi Darryl. That looks like potentially a great fit for us. I have sent in a request on the website to try the beta version. Thanks!

While this isn't a solution within Confluence, you might want to check out our new Targeted Search add-on for Confluence, which you can configure to search spaces or space categories, as well as use hierarchies of labels to provide a search experience much like shopping on Zappos or Amazon.

Apologies for the product pitch here, but perhaps it will help.

Yeah. I'm coming to dislike the whole concept of feature voting in this kind of context. Too often a marketing subterfuge and an excuse for not doing the common sense / right thing for the core product.

This request is nearing its 9th birthday and is unassigned so I wouldn't get my hopes up, unfortunately. :-/

Plus 1 here. We find that in many cases it's useful and easier for our users to manage multiple related spaces than it is to, say, shoehorn a set of related working groups into a single space, split up via page-level permissioning, which can quickly get hairy to manage. That makes it important that search be configurable such that a single search can be run across – and only across – a defined set of spaces.

We are looking for this functionality - kind of assuming it was already there as it seems this is quite a basic feature for a search macro.
