For example, I searched for "Fish Painter" hoping to find the cart "Fish Painter Deluxe." This cart did not show up in the list of results. Searching for the word "Deluxe" however, worked. "Fish" does not work.

Another example, I searched for "Star Picker-upper." The only search that worked was "Picker." "Star" and "Star Picker-upper" did not work.

I've noticed similar things.
