You're doing it wrong. Using quicksearch is not the best way to get games, since most people use the game browser.
You'll want to either host a game in the game browser (you can access it in one of the tabs on the left), or join someone else's game there. Though if you do use the game browser, take note of the "rank" system. The right-most column will show the "rank" of the player hosting it, e.g. conscript, private, master sergeant, brigadier. You will most likely get booted from a game if you're considered not good enough. For someone who's played only 7 games, I'd suggest joining conscript,private or lance corporal games, or hosting a game yourself.
EDIT: Just checked your ESO. It appears you won 5 out of 7 games, which is pretty good for someone new to the game. You're currently pr 21 (2nd Lieutenant)- check this in the Home Cities tab, bottom right. So probably master sergeant, 2nd lieutenant, 1st lieutenant games then. Though your rank may be inflated since it's only been 7 games. It'll stabilize to your true-ish rank when you've played more.
