i just came to a telegram message from one of my friend about a weird thing on google search. Just type "2 * 2" (without spaces) and it shows up a calculator and the search results then just search for "-2 * 2"(without spaces) and it lasts for 5 seconds to just show the calculator and there is no search result there. it's the same weird result for "-3 * 3"(without spaces) but for example for "-6 * 3"(without spaces) i get search results on time.
Update: after a while the problem with time lag is gone, but i stiil don't see the search results for "-2 * 2 " (without spaces) and it only shows up caclulator
