[FEATURE] Add support for bangs in search engines

[noClaps]

Originally posted on DiscuitSuggestions.

Once search is ready, it can be used for bangs in search engines that support it, like Kagi or DuckDuckGo. This would require the search URL to have the format https://discuit.net/search?q=[search query] or something similar.

• Bangs | Kagi's Documentation
• DuckDuckGo New !Bang

If someone uses a different search engine with support for bangs, they can add it here.
