[Wikitech-l] Image search

I've been contributing to Wikipedia since 2001 and to Wikimedia Commons since 2005. I'm not new to this. Wikimedia Commons now has millions of images and thousands of categories. But it's really hard to find anything. Today I was looking for photos of buildings that have an exterior lantern on their corner. This is common in the countryside, where there are no streetlights and no other buildings nearby. You put a lantern on the outside of your house, and you put it on the corner to cover two sides with one lamp. So there are categories for buildings and for houses. And by country and by county. And by building material. And there is a category for exterior lanterns, but none of the photos there are really corner-mounted. When I arrive at Commons, there is a search box and so I type "exterior lantern corner", but all it does is to search text content and descriptions. So I get lots of hits in scanned documents, which is not what I wanted. I can limit my search to the "File" namespace, but that includes both JPEG photos and PDF documents. Here are indeed some corner lamps, but not the rural kind I wanted, https://commons.wikimedia.org/wiki/File:Tinghuset_(lanterne).jpg https://commons.wikimedia.org/wiki/File:Fanal_públic_LED.JPG Here is what I search, but the lamp (in the upper left) is too small to be useful in this photo, https://commons.wikimedia.org/wiki/File:Vårdinge_församlingshem.JPG This is where I want to find more images like these, not in the same category, just similar photos. Surely, such a search function could be implemented in 2020, in addition to our current text search? Hasn't anybody done this already? -- Lars Aronsson (lars(a)aronsson.se) Linköping
