SEARCH FUNCTIONS: IS THERE A "USER MANUAL" TO HELP NEW USERS, PLEASE?

AS IN THE SUBJECT LINE, HOW DO I SEARCH FOR: STAR TREK DISCOVERY S03 720P; THE YOUNG AND THE RESTLESS S049?

FOR EPISODES THAT SHOW NO SEEDS, DOES THAT MEAN THAT THEY WERE DELETED? IS THERE AN "ARCHIVES" AREA FROM WHICH TO ACCESS SUCH EPISODES?

THANK YOU!!!!!

THANK ALL THE VIEWERS/USERS WHO ARE SO OBLIGING IN SHARING KNOWLEDGE AND HELPING NEWBIES. HOPE SOMEONE DOES THE SAME TO YOU.
