why search this url will not show any results "https://www.Myowndomain.com/join/?sale=anniversary-20

I have a word document inside my SharePoint online site with this content:-

Now if i do a search using "Try this for the search" >> i will get correct results:-

if i try to search using "www.yahoo.com/Search?123" i will also get the correct result:-

But if i search using "https://www.Myowndomain.com/join/?sale=anniversary-2023 or even https://www.Myowndomain.com/*

i will not get any results:-

so why the search is ignoring some links? and can we fix this?

Thanks
