I am building a Q&A website such as Stack Overflow and now I want to add its search capabilities.
I want to use the Google Search API, but one of my friends said that it’s better to have your own search engine, because Google does not index all pages (especially recently added pages), and also has a negative effect on site ranking.
My question is whether these statements are true or not, and what is the best way to search on this site?
