A little while ago, I asked this question and a senior member voted to close it saying it's a 'trivia' question. He said:
Please do preliminary research before posting questions to H:SE as How to Ask points out, we're not trying to replace google.
The rule for closing questions as 'trivia' says:
Requests for trivia or basic historical facts are off-topic if they can be easily answered by looking up the relevant topic on Wikipedia. We're trying to complement common historical references, not duplicate them.
My question is, are questions that can be answered on history.SE by searching Google with little efforts off-topic? If so, does the rule for closing questions as 'trivia' needs to be updated?
