We have 2 different search criteria that our system looks for,
1) Anything on Google that has "Royal Marines" but without (tonga, music) no disrespect to the Royal Marine band but as they were a show event 80% of the time and get lots of reports news stories about them, around 10 news articles a day, so had to leave them out of the search.
2) Second is a search that goes through MOD Oracle, it flags up anything with Iraq, Afghanistan and Royal Navy. So that isn't specific to the Royal Marines.
The second may not be 100% relevant to anyone going in as RM Recruit, but is extremely helpful to those trying for the POC and AIB. That's the main reason we have that one, as officer candidates are expected to know just about everything going off in the public domain.
