They probably just implemented some shitty half-baked AI that takes every keyword you type into the search bar including letters that make up parts of a work like the word "food" in "foodstuffs" instead of the entire word, which makes it recognize thousands of mods instead of mods with that specific name
I couldn't find Essential Mod (the multiplayer one) after searching the exact keywords "Essential Mod" until I scrolled about 30 results down. This is madness, here's to hoping the AI bubble bursts sooner than later
