I've previously used polyclar during this brew after troublesome clearing and with some faffing got a crystal clear lager.
More recently I used gelatine in a secondary FV before refridgerating and didn't need to use polyclar.
How Do They Do It?

Re: How Do They Do It?
The results:
Single hopped Green Bullet was made on 20 June, stable at 1.015 by 27 June. Racked into 4" neck FV 29 June.
Into fridge at about 5C for four days, racked into corny and then into freezer at 2C for three days. This was chosen because it has a very strong hop taste and I want to put it though a flash cooler and a cold font in about 6 weeks.
The filter cartridge is 0.5 micron. 5l of Star San to sanitise the filter and cornies:
I was very pleased to see that the filter housing was very nearly empty of Star San at the end. I had visions of tying the cartridge to a piece of string and wizzing it round my head to get the Star San out.
After purging with CO2, It was filtered:
On the right, the "filtered" result. On the left, the same but given 30 seconds in the nuker:
So this was pretty much a waste of time....
This regime with a 0.5 micron filter does not get rid of chill haze.
When back flushing the filter with water, a considerable amount of "yellow" came out - yeast?
I am now hoping that six weeks at 2C will drop the haze.....

Re: How Do They Do It?
I've never had much luck with Polyclar, I've used 5g and 10g per batch respectively, the two times I've used it, and found it didn't like to drop out and was easily disturbed (I added it to the keg with a shortened dip tube). I know some people have used it to good success though.
Isinglass works well if you get the good stuff from H&G, it will remove some chill haze too if you add it when the beer is ice cold (0C).
I've found the absolute best clarifier is just cold conditioning as long as you can afford to wait. Keep your keg / carboy as cold as possible for a few weeks (colder the better), and it should clarify naturally. Beer can be kept as cold as -2C or maybe even a little colder without freezing.
