Ah I get it. For those who want to use the advanced search as a custom feed for friends, a paid account is needed. 

Another question for you: how do I find out what’s the address associated to my primal wallet? Currently it shows the address I use on Damus. I haven’t tried Primal in a long time 

 Best way to find your primal lightning address would be to access your the Primal Wallet and hit the “Receive” button. In there you’ll have two options, your lightning address and your btc on-chain address. Lmk if you need more help finding it  

 That makes a lot of sense. Thank you
