Today I was searching Google for the keyword wikipedia. I found something new on the search results. I found a search button text box and button under the search result of wikipedia mentioning to search site wikipedia. I tested it for few popular keywords and for all them it had this search box. From the test I did it is evident that site with more than thousands of articles get this box else just the site links šŸ˜‰

Happy Googling šŸ˜€
