Hoping to boost the relevance of your searches, Flickr introduces what it calls “similarity search.” This new feature will help you look for photos that are visually similar to the one you’re currently looking at. The example it gave was doing a search for a cactus. When you input the search term, just hover over the image that looks the most like what you want. Afterwards, select the “…” menu. From there, you get an option to “Search for similar photos” and you’re good to go. This feature will hopefully help you find the images you want quicker.
