FIST (Free Image Search Tool) seems to be a powerful tool to find freely usable images to illustrate Wikipedia/etc articles. The tool is recommended by Wikipedia.
Unfortunately, I most often get 0 articles found
... there must be something that I failed to understand. There is no help page nor tutorial either.
QUESTION: How to make at least a few results appear?
Example with "Thouars" (Wikipedia, FIST request)
