Claims to a image search engine
An image search engine should come up in addition to good results with the appropriate filter options, and in the case of "disreputable" search terms not to degenerate into a porn site. These three points we will verify on the basis of the following test scenarios:
- The topic of the "correct" results, we check on the basis of a rather rare search term - we search for the Hamburger "Band stone fish".
- We vary the filter options in the search results.
- The topic of youth protection, we check on the basis of the ambiguous Name, the Ingolstadt-based Band "Slut" (English for "slut").
Picsearch Image Search
Founded in 2000, search engine Picsearch found in the German version, in particular, national images.
- Picsearch find, unfortunately, only a suitable subject for the "Band stone fish".
- Alignment, colors, and sizes of the images found in a bar next to the search results set. A great Feature is the search of GIF-animations.
- The search "Slut" leads to numerous band photos, and has no pornographic content. Other more salacious search terms picsearch remains modest.

Google Search Images
