or you could use DuckDuckGo, its !bang feature lets you directly search on a website you want. searching "Beatles !mb" will redirect you to MusicBrainz' search results, for example.
Firefox has keyword bookmarks which is basically identical to bangs but you can customize them to your preference and they don't require sending your query to a third-party remote service.
Just set the "Keyword" option in a bookmark and type mykeyword foo in the URL bar to search using your bookmark mykeyword. I use a lot of one-character keywords such as m for https://www.google.ca/maps?q=%s, g for https://www.google.com/search?q=%s, d for https://www.dndbeyond.com/search?q=%s and similar. I also have a keyword e which runs a bookmarklet that fills in a one-time email into the currently focused input field.
IDK, maybe I have a particularly bad memory but it is basically as easy for me to bookmark a URL as it is to lookup and remember a bang that they defined. Plus local will always be faster, more private and more secure.
