Do someone knows how to set Hoogle as a Google Chrome search engine?
Hackage is already there on those steps:
From the Hoogle manual:
Chrome Integration As a keyword search: With a keyword search you can type h map directly into the location bar to perform a Hoogle search. Go to the Hoogle website in Chrome, right-click in the Hoogle search field and select "Add as a search engine...". Give it a keyword such as "h".
