We need to be able to search shared albums in Lightroom so that all team members could easily find a specific image by keyword, tag, attribute, ...etc.
While this is primarily a user community forum, this "Ideas" section does make its way into the priority list for new feature development. I can see that this thread, although almost a year old, has just 6 upvotes (I just added a 7th). Compared to many other feature requests, that puts this one at a relatively low priority, in my personal opinion, as there are others with far more votes than this one. If you know of lots of other people who need or want this feature, have them check in here and add an upvote.
