title: Difference between "By.partialLinkText" and "By.LinkText" in Selenium?
body: <p>I tried to find a element based on the Text i can see on screen on the Wikipedia page. Now, firstly i tried <code>driver.findElement(By.LinkText("English"));</code> with no results. 
  But then i tried the code below with <code>driver.findElement(By.partialLinkText("English"));</code> instead and it worked.
  Can someone explain me based on that wikipedia page, why is that? Because the example is really simple and i don't know why <code>driver.findElement(By.LinkText("English"));</code> does not work?</p>
  
  <pre><code>driver.get("http://www.wikipedia.org");
  WebElement link;
  link = driver.findElement(By.partialLinkText("English"));
  link.click();
  </code></pre>
