 ## Fallback search behaviour
 
-The plugin will use Google as a fallback if the docs site for a search context does not have a search function. You can set the fallback search engine to DuckDuckGo by setting  `FRONTEND_SEARCH_FALLBACK='duckduckgo'` in your `~/.zshrc` file before Oh My Zsh is sourced.

+## DuckDuckGo Lucky Search
+
+Enable DuckDuckGo's "ducky" (lucky) search feature to automatically access the top search result. This feature
+is optimized for DuckDuckGo, as Google redirects to an intermediate page. The FRONTEND_SEARCH_FALLBACK_LUCKY
+environment variable triggers the use of DuckDuckGo's lucky search, rendering the FRONTEND_SEARCH_FALLBACK
+setting unnecessary in this context.
