No problem. I have never made enough of this facet, but it’s very powerful. Imagine trying to guess login details when with every wrong guess you are disconnected, etc. There is more to it, but the weird network behaviour is that at the data level in routing you always know the data exists, it must. So any type of search at that level is banned.
It’s unrelated to searches in upper layers (for indexing data we are fine, then search indexes). So does not mean we cannot have search engines, just they will search over known data. I hope that makes sense. I realise I am not explaining well here, but in the middle of crust/routing API issues so will come back no problem and go into it more deeply. It is it’s own thread I think though and very useful.
