Well, my mentor used to yell "RTFM, doood!". Which I did. And got the answer more than once.
I would like to agree that(as a sibling comment points out) this depends on his personality and relation to the team.
When it was my chance to mentor, I would sit with the junior guy and just talk about the context and problem at hand. Talk about the keywords and then form a query to google. I would sometimes intentionally put in the wrong query and then refine it for better results. It worked.
But juniors are sometimes bad at retaining processes and a similar query would pop up in a few weeks again. Then I would just send them a lmgtfy link (which is a dick move. Don't do this). Have some compassion, patience and empathy. It might take longer but that guy will thank you in the long run.
