Every time I post these guides, there is always feedback on things that can improve, or I got wrong. Please do share, as it is the best way for these to evolve!
Another paid search option is Metager - since Mullvads Leta shut down, i looked for something to switch to and Metager fits the bill: no tracking shit, no ads, a good search with working blacklists, and a configurable cost for the search depending on which indexes you want to use and if you want to use search suggestions. It also taught me to use search shortcuts which i was too lazy to use before - no need to use my tokens when i know i want a wikipedia result.
