I find it confusing and hard to search for all topics/images/places etc. on or about a particular event or place. I mainly concern myself with researching the Battle of Hong Kong, and I find it hard to search, for example, of all photos of soldiers in combat on Gwulo. It would be greatly beneficial if we added an option to search by date (e.g. search only photos taken in Dec 1941 instead of having to view the gallery of all photos of the 1940s), or standardizing the tag function so that e.g. "Pillbox" and "Pill Box" don't appear as seperate tags.
