I'm a heavy Chrome user and while typing in yet another url, I noticed a strange behavoir whereby the ombnibar (url bar) changed to say "Search MyCo JIRA:" and allowed me to directly search my jira site via the private search page. Same works for wikipedia, confluence, and others.
How does chrome recognize this site is searchable and how to submit the request?
Here is the key combo I came across: - open chrome and place cursor into an empty omnibar. - type
wikipedia.org:<space>
that is the domain, a colon, and a space.
The omnibar changes to show a spyglass button saying "Search Wikipedia (en):"
This is so cool I want to know how to do this to my site.
