The most frustrating thing about Netflix is trying to find something to watch. Oh, there's no shortage of movies and TV shows available for streaming. The company currently lists over 3,600 titles but searching such a huge selection is overwhelming.

It seems you're only shown the same 200 or so titles no matter how often you scroll, and most of us can scroll for hours before finding something to watch. Netflix puts movies and shows into categories such as 'dramas', 'romance', 'comedies' and 'horror', but we still see a limited number of titles within the genres.

What most Netflix subscribers don't realize is that there are secret codes that make it easier to find something you didn't know was there. These secret codes or category IDs, break each genre into sub-genres.

In the horror" category, you'll find "Zombie Horror Movies", "Horror documentaries from the 1960s" and "campy horror movies". There are thousands, approximately 27,000 sub-categories, in fact, since Netflix puts each title into multiple categories.

To browse or search with the secret codes, you must use a computer or smartphone browser and enter: "netflix.com/browse/genre/" followed by the secret code or number.

For "Deep Sea Horror Movies," for example, you should enter "www.netflix.com/browse/genre/45028"

There are more than 100 million Netflix subscribers in the world, and chances are only a handful know about this sub-category indexing. It can still be frustrating entering the numbers and searching for something you haven't seen before, but it's the only way I've found to see everything Netflix has to offer.
