> Google Site Search, which can be used to power the search for websites has started showing Ads (miserably even competitors ads).
Indeed. It is unbelievably bad! I was recently trying to integrate Google Site Search into https://share.cocalc.com/, and on many test queries I would see an entire page of ads for our competitors (or completely irrelevant) products. E.g., if I searched for "julia" (thinking of the programming language), I would get a full page of ads for jewelry! I ended up just building a little search box from scratch myself that pops up another browser tab with a normal Google search that has "site:share.cocalc.com" pre-pended to it. This seems to work surprisingly well -- there can be ads (it's just a normal google search), but they are at least completely blocked if you have an adblocker installed. What is the drawback of this approach of just using site: rather than Google site search or expertrec.com?
