Sanne Grinovero commented on HSEARCH-212:
-----------------------------------------

I am confident it is safe to be used, still I'm not sure if it is really faster.
I would use it for myself, as I believe on theoretical basis it should be faster, but still didn't manage to proof it.
If you think I could get more feedback by enabling it in Beta1 i will document it, but are we still having the option to leave it out in ga after being in beta?
