You can find answers to common questions on Wikipedia by visiting the website. Type your query into the text box located at the bottom center of the landing page, beneath Wikipedia's logo.
The first thing you see on Wikipedia's landing page is its logo, surrounded by ten of the most commonly used languages to choose from. Click on your native language. If your native language is not seen in the top ten simply use the drop-down box found right below the logo, next to the search box. Choose your native language from the comprehensive list, organized A-Z, and use the text box to the left to type in your question. You can either search in full sentences or by using keywords.
Popular queries appear below the text box as you type. Hit the Enter key or press the button on the right-hand side to run your search. You are then taken to the result page. From there you can navigate the list of all items on Wikipedia relevant to your search terms and browse the various articles. No matter where you navigate to from there, a search text box is available at the top right-hand side of the Wikipedia page.
