This may not technically be a problem, but it is for me and visitors to Zenfolio sites.
Why can we not browse the results of a search? If I find 20 pictures of X then the most obvious thing I would want to do is browse that result, or perhaps view it as a slide show. But if I try to do that, I find myself browsing the parent gallery of the image I have selected. Other pics in that gallery may have no relationship to my search result.
This is a problem because a) it is completely un-intuitive and potentially very confusing for visitors b) it makes the site owner look incompetent.
There is no point in being able to use keywords and have multiple galleries or collections - possibly with images in multiple collections - if the search result ignores that structure
